Answer:
x³ + 11x² + 28x
Step-by-step explanation:
(x + 4)(x² + 7x)
Each term in the second factor is multiplied by each term in the forst factor, that is
x(x² + 7x) + 4(x² + 7x) ← distribute parenthesis
= x³ + 7x² + 4x² + 28x ← collect like terms
= x³ + 11x² + 28x
[tex] \huge \underline{ \sf \: Solution}[/tex]
[tex](x + 4)( {x}^{2} + 7x) \\ = x( {x}^{2} + 7x) + 4( {x}^{2} + 7x) \\ = {x}^{3} + {7x}^{2} + {4x}^{2} + 28x \\ = {x}^{3} + {11x}^{2} + 28x [/tex]

A line passes through the point (8, -7) and has a slope of
3/4
Write an equation in slope-intercept form for this line.
Answer:
y = 3/4x - 13
Step-by-step explanation:
As we already know the slope, we just need to find the y-intercept.
y = 3/4x +b
-7 = 3/4(8) + b
-7 = 6 + b
-13 = b
y = 3/4x - 13

Is this exponential growth or decay?
What is the rate of growth or decay?
What was the initial amount?
help ASAP
true or false?
and please tell me how to solve it❤
Answer:
True
Step-by-step explanation:
[tex]\frac{x - y }{x + y}=-1[/tex] ---------------(I)
Cross multiply
x - y = -1*(x + y)
x - y = (-1)*x + y * (-1)
x - y = -x - y
x - y + x = - y
2x - y = -y
2x = -y + y
2x = 0
x = 0
Plugin x = 0 in (I)
[tex]\frac{0-y}{0+ y} = -1\\\\\frac{-y}{y}=-1\\\\-1 = -1[/tex]
So , true
Step-by-step explanation:
This is true. -1 =-1

essentially the fourth option is the best
Answer:
option 3
Step-by-step explanation:
NO LINKS OR I WILL REPORT!!! But pls help meee pls I’ve posted this so many times just help me out pls Calculate the scale factor of ABC to DEF. Enter answer as a whole number
or as a fraction in lowest terms, using the slash mark (/) for the fraction bar.
Answer:
The scale factor is 8.
Segment AC is congruent to segment FD, and the other 2 sides are congruent because this is an isosceles triangle.
Triangle ABC can transform to Triangle DEF after a scale factor (multiplying each side by the same value) of 8.
Hope this helps!

Use the Graph of the parabola to fill in the table
Answer:
a) Upwards
b) x = -1
c) (-1,-9)
d) x intercepts; (2,0) and (-4,0)
y intercept is (0,-8)
Step-by-step explanation:
a) As we can see, the parabola faces upwards
b) To find the axis of symmetry equation, we look at the plot of the graph and see the point through the vertex of the parabola that exactly divides the parabola into two equal parts
The x-value that the line passes through here is the point x = -1 and that is the equation of the axis of symmetry
c) The vertex represents the lowest point of the circle here,
As we can see, this is the point through which the axis of symmetry passes through to make a symmetrical division of the parabola
We have the coordinates of this point as
(-1,-9)
d) The intercepts
The x-intercept are the two points in which the parabola crosses the x-axis
We have this point as 2 and -4
The x-intercepts are at the points (2,0) and (-4,0)
For the y-intercept; it is the y-coordinate of the point at which the parabola crosses the y-axis and this is the point (0,-8)
What point of the number line represents the sum of 3/4 + 3/4
Answer:
C
Step-by-step explanation:
3/4+3/4=6/4=1 2/4=1 1/2
C is located halfway between 1 and 2, so you know it is 1 1/2.
A fraction is a way to describe a part of a whole. The number on the number line is represented by point C.
What is a Fraction?A fraction is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25.
To plot the fraction on the number line, the sum of the number line is needed to be found. Therefore, the sum of the number line can be written as,
[tex]\rm Sum = \dfrac34 + \dfrac34 = \dfrac64[/tex]
Thus, the sum of the fraction is (6/4), which can also be written as 1.50.
The number on the number line is represented by point C.

Answer:
y = x² + 5
Step-by-step explanation:
When x = 1:
y = x² + 5
y = 1² + 5
y = 6
When x = 2:
y = x² + 5
y = 2² + 5
y = 9
When x = 3:

Alberto invests $4,571 in a retirement account with a fixed annual interest rate of 3% compounded 6 times per year. What will the account balance be after 18 years?
A) $7,833.32
B) $7,162.06
C) $7,602.38
D) $6,985.59
Answer:
A) $7,833.32
Step-by-step explanation:
Given data
Principal= $4,571
Rate=3%
n= 6
Time = 18 years
The expression for compound interest is
A=P(1+r/n)^nt
substitute
A= 4571(1+0.03/6)^6*18
A= 4571(1+0.03/6)^6*18
A= 4571(1+0.005)^6*18
A= 4571(1.005)^6*18
A= 4571(1.005)^108
A=4571*1.7136
A=$7832.86
Hence the approximate amount is A) $7,833.32

Which lists all the multiples of 6 that are less than 20?
6, 9, 12, 15, 18
6, 12
6, 12, 18
6, 12, 18, 24
Answer:
C
Step-by-step explanation
An easy way to figure is to see if all of the numbers in that group can be divided by 6.
In this first one, 9 and 15 are not divisible by 6.
In the second one 6, 12 are multiples ok 6 but there is one more.
In the last one 24 is over the 20 limit.
So, C is correct.
Evaluate the expression below when x = 9 and y = 12.
4(x + 6) - 3(y + 4)
