Answer:
9 x^2 + 24 x + 16 or (3 x + 4)^2
Step-by-step explanation:
Simplify the following:
(3 x + 4) (3 x + 4)
(3 x + 4) (3 x + 4) = (3 x + 4)^2:
Answer: |
| (3 x + 4)^2
or
Expand the following:
(3 x + 4) (3 x + 4)
(3 x + 4) (3 x + 4) = (3 x + 4)^2:
(3 x + 4)^2
(3 x + 4) (3 x + 4) = (3 x) (3 x) + (3 x) (4) + (4) (3 x) + (4) (4):
3 3 x x + 4 3 x + 4 3 x + 4 4
3 x×3 x = 3×3 x^2:
9 x^2 + 4 3 x + 4 3 x + 4 4
3×3 = 9:
9 x^2 + 4 3 x + 4 3 x + 4 4
4×3 = 12:
9 x^2 + 4 3 x + 12 x + 4 4
4×3 = 12:
9 x^2 + 12 x + 12 x + 4 4
4×4 = 16:
9 x^2 + 12 x + 12 x + 16
Grouping like terms, 9 x^2 + 12 x + 12 x + 16 = 9 x^2 + (12 x + 12 x) + 16:

Classify the following polynomial as a monomial, binomial, trinomial, or none of these.
x + y + z
Monomial
Trinomial
Binomial
None of these
Answer:
Trinomial.
Step-by-step explanation:
A monomial has one term. A binomial has two terms. A trinomial has 3 terms.
x + y + z has 3 terms; x, y, z. So it is considered a trinomial.

Madison deposited $7,000 into an account that earns simple interest. After 36 months, Madison had earned $840 in interest. What was the interest rate of the account?
12 percent
Step-by-step explanation:
well because if you divide 840 by 36 you get 23.33 if you divide 840 by 3 its 280, if you divide that by 23.33 you get 12 percent.
Evaluate the algebraic expression 4v-3 if v= -5.explain
Answer:
-23
Step-by-step explanation:
Given 4v-3
evaluate when v = -5
So basically we want to find the value of the expression when the variable (v) equals -5
so
* plug in -5 for v*
4(-5)-3
4*-5=-20
-20-3=-23
So we can conclude that when v = -5 the value of the expression is -23
Answer:
4v-3 = -23Explanation:
given the expression: 4v-3
if v = -5
4v-3 (let's subsitute v)
4v-3 = 4×(-5)-3
4v-3 = -20 - 3
4v-3 = -23

→XxKim02xXFind the rule. Solve for n. Х Y 4 3 6 5 7 6 10 n Rule:
Answer:
n = 9
Step-by-step explanation:
Here we have the table:
X Y
4 3
6 5
7 6
10 n
First, we want to find the rule.
in the first pair we have:
x = 4
y = 3
We can see that the y-value is one smaller than the x-value
y = 3 = 4 - 1 = x - 1
For the second pair we have:
x = 6, y = 5
We again can see that the y-value is one smaller than the x-value
y = 5 = 6 - 1 = x - 1
For the third pair we have:
x = 7, y = 6
Again, can see that the y-value is one smaller than the x-value.
y = 6 = 7 - 1 = x - 1
We can conclude that the rule is:
y = x - 1
For the last pair, we have:
x = 10, y = n
Then:
n = 10 - 1 = 9
n = 9
Then the table is:
X Y

Oliver is performing an experiment by spinning a metal weight around on the end of a nylon thread. How far does the metal weight travel if it
completes 10 revolutions on the end of a 0.88 m thread?
Give your answer correct to one decimal place.
Answer:
27.7m
Step-by-step explanation:
Step 1
We find the Circumference of the nylon thread.
The formula = 2πr
The diameter of the thread = 0.88m
Radius = Diameter/2
= 0.88m/2
= 0.44m
Circumference = 2 × π × 0.44m
= 2.7646015352m
Approximately = 2.765m
Step 2
We calculate the distance
Number of revolutions = 10
Therefore, the Distance or how far the metal weight can travel =
Circumference of the wheel × Number of revolutions
= 2.765m × 10
= 27.65m
Approximately to 1 decimal place = 27.7m
Which shows the expression below simplified? (4.9 x 108) ÷ (7 x 105)

Find the distance between y= 2/3x+4 and y=2/3x-1 1. Round your answer to the nearest tenth. The distance is about units.
Answer:
12.5
Step-by-step explanation:
y= 2/3x+4 and y=2/3x-1 1 are parallel: slope 1 = 2/3 = slope 2
the distance of line 1 and line 2 is the segment length of perpendicular line intercept two parallel lines. In other words, the distance between two parallel lines in the plane is the minimum distance between any two points lying on the lines. It equals the perpendicular distance from any point on one line to the other line.
equation of the perpendicular line pass the y intercept of line 1: y=2/3x+4 (0,4) is y = -3/2x + 4, which intercept with line 1 at (0,4)
solve the intercept of perpendicular line with line 2: get (6.9 , -6.4)
y=-3/2x + 4 and y=2/3x-1 1 (you should be able to solve this part by self)
distance of (0,4) and (6.9,-6.4): √(6.9-0)²+(-6.4-4)² = √155.77 = 12.48 ≈ 12.5

Identify the type of sequence and the common ratio or difference.
Can I get help with this problem please?
Answer:
B
Step-by-step explanation:
To find the y- intercept let x = 0
From the table for f(x)
When x = 0 → f(x) = - 4
That is the y- intercept = - 4
Given
g(x) = 3 [tex](2)^{x}[/tex]
let x = 0 , then
g(0) = 3 [tex](2)^{0}[/tex] [ [tex]2^{0}[/tex] = 1 ]
= 3 × 1
= 3
That is the y- intercept = 3
Thus the y- intercept of g(x) is greater → B

what is square root of 5x^4-6x^5+x^6+16x^3-8x^2-8x+4 ?
help me pleasee !
Answer:
y = (x + 1)(x - 0.586) ( x - 3.414)
Step-by-step explanation:
I sure wouldn't recommend doing this by trial and error.
I made a graph of which you can see. Every time this monster touches the x axis and speeds away upward is two equal roots of y. So the square root would be one of each of them.
y = (x + 1)^2 (x - 0.586)^2 (x - 3.414)^2
are the listed roots.
The square root is
y = (x + 1)(x - 0.586) ( x - 3.414)
Do I know that this is right? I don't. But I can tell you this: if you multiply 1^2 * (-0.586)^2 * (- 3.414)^2
you get 4 just as you should. Amazing that we have tools that do that sort of thing.

Jacob has $25 worth of baseball trading cards. His sister, Bonita, has some trading cards and
his sister, Madison, has $7 worth of trading cards. Bonita cards are worth $2 each. Bonita's
and Madison's trading cards together are worth more than Jacob's cards. How many trading
cards, x, could Bonita have?
a) Write the inequality.
b) Solve the inequality using properties of operations.
c) Represent the solution(s) on a number line.
HHHHHHHHHHHHH
15
10
d) Use substitution to determine whether 8, 9, 12, or 15 are solutions to the inequality.
Answer:
2x + 7 > 25 ; 9
Step-by-step explanation:
Total worth of Jacob's cards = $25
Number of Bonita's card = x
Worth of Bonita's card = $2 each
Worth of Madison card = $7
Bonita and Madison cards are worth more than Jacob's card
The inequality
Bonita = 2x ; Madison = 7
2x + 7 > 25
Solving for x
2x > 25 - 7
2x > 18
x > 18 /2
x > 9

Please help me In a geometric series, each term is 21% less than the previous term. What is the value of r for this
geometric series?
0.79
0.21
1
1.21
1.21
Answer:
A
Step-by-step explanation:
You need a value that keeps 79% of the previous value. 79% is 0.79 as a decimal.
You get that by taking 100% of the value and subtracting 21% of the value. Said easier (100% x - 21%x = 79% of x.
r = 0.79
If 30% of a number equals 25, find 60% of that number.
(PLEASE DONT SEND ME NO LINK EXPECTING IT TO WORK THAN WHEN I TELL U , U DONT REPLY)
Answer:
14.94
Step by step:
25/30 = 83.333
.30x83 = 24.9
.60 x 24.9 = 14.94
Answer:
50
Step-by-step explanation:
Let's set the number as "x". So, 30% of x is 25. We can then write this equation.
30% * x = 25
Change 30% to a decimal
0.3 * x = 25
Divide both sides by 0.3
x = 83 and 1/3
Then, to find 60% of this number, write this equation.
60% * 83 1/3 =
0.6 * 83 1/3 =
50
