find the product (3x - 5) (3x + 5)
Answer:
9x ^2 − 25
Explanation:
( a + b ) ( a − b ) = a ^2 − ^b 2
substitute a with 3 x and b with 5:
( 3 x + 5 ) ( 3 x − 5 ) = ( 3 x ) 2 −5^ 2 = 9 x ^2 − 25
( 3 x + 5 )( 3 x − 5 ) = 9 x ^2 − 25
Answer:
9x² - 25
Step-by-step explanation:
(a - b)(a + b)= a² - b²
a = 3x ; b = 5
(3x - 5 )(3x + 5)= (3x)² - 5²
= 3²x² - 25
= 9x² - 25

Write what is left. 6y+4y=10
Combine like terms 10y=10
y=1
x=3
Check 3=3(1)
6+4=10
So this solution is correct

suppose that the functions s and t are defined for all real numbers x as follows
s(x)=x+6
t(x)=2x^2
write the expressions for (s+t)(x) and (s*t)(x) and evaluate (s-t)(2)
Answer:
(s+t)(x) = s(x) + t(x)
(s*t)(x) = 2x³ + 4x²
Step-by-step explanation:
(s+t)(x) = s(x) + t(x)
= x + 2 + 2x²
= 2x² + x + 2
(s*t)(x) = s(x) * t(x)
= (x + 2) * 2x²
= 2x³ + 4x²

solve 3x+ k= c for x.
The value of variable x in the equation is x = c - k / 3
How to make a variable subject of the formula?3x+ k = c
let's find x or make it the subject of the formula,
3x + k = c
subtract k from both sides of the equation
3x + k - k = c - k
3x = c - k
divide both sides by 3
3x / 3 = c - k / 3
Therefore,
x = c - k / 3

solve in systems by substitution y=x+2 and 3x+3y=6
Answer:
x = 0, y = 2
Step-by-step explanation:
Substitute the first equation into the second equation so 3x + 3(x+2) = 6. Simplify this to get x = 0. Plug x = 0 back into the first equation to get y = 2.
Answer:
x = 0, y = 2
Step-by-step explanation:
y = x + 2
3x + 3y = 6
3x + 3(x + 2) =6
3x + 3x +6 = 6
6x = 0
x = 0
y = x + 2 = 0 + 2 = 2
The ratio of the perimeter of a square A and square B is 4:3. The side of square B is 3 m less than the side
of square A. What is the length of the side of square A?
please answer
Answer:
x = 12
Step-by-step explanation:
x = length of side of square A
'x-3' represents length of side of square B
Perimeter of square A = 4x
Perimeter of square A = 4x - 12
we can set up the following proportion based on ratio of 4:3
4x / 4 = 4x - 12 / 3
cross-multiply:
4(3x) = 4(4x-12)
12x = 16x - 48
-4x = -48
x = 12
Determine whether the sequence is arithmetic. If it is, determine the common difference.
--12, 10, 32, 54,...
Answer:
The sequence is arithmetic
Step-by-step explanation:
Here we want to determine the sequence is arithmetic
If the sequence was arithmetic, the difference between the terms would be constant
We have this as;
10-(-12) = 22
32-10 = 22
54-32 = 22
As we can see, the difference is constant and so we have it that the sequence is arithmetic

What's the number that is halfway between numbers 0 and 121?
Halfway Between 0 and 121
Halfway Between
When you ask "What number is halfway between 0 and 121?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=0 and Y=121.
Halfway Between Line
To find the number halfway between 0 and 121, we use the following formula:
(X + Y)/2 = Halfway Between
When we enter 0 and 121 into our formula, we get:
(0 + 121)/2 = 60.5
Thus, the number halfway between 0 and 121 is 60.5
Answer:
solution given;
half way between 0 and 121=?
let a=0
and
b=121
we have
halfway =[a+b]/2=[0+121]/2=60.5
half way between 0 and 121 is 60.5

(points on a circle) PLEASE HELP THIS IS DUE TONIGHT
A circle is centered at C(0,0)C(0,0)C, left parenthesis, 0, comma, 0, right parenthesis. The point M(0,\sqrt{38})M(0,38 )M, left parenthesis, 0, comma, square root of, 38, end square root, right parenthesis is on the circle.
Where does the point N(-5,-3)N(−5,−3)N, left parenthesis, minus, 5, comma, minus, 3, right parenthesis lie?
Answer:
Inside the circle, a distance of [tex]\sqrt{34}[/tex] from the center of the circle.
Step-by-step explanation:
Center of circle is at (0,0)
One point of the circle is at (0,[tex]\sqrt{38}[/tex])
Since the only known point is in the y-axis, the radius of the circle must be [tex]\sqrt{38}[/tex].
[tex]\sqrt{38}[/tex] = 6.164
So the point (-5,-3) is still inside the circle as the distance from point (-5,-3) to the center of the circle is [tex]\sqrt{(5)^2+(-3)^2}[/tex] or [tex]\sqrt{34}[/tex] which is less than the radius of the circle.
Point N(-5, -3) lies inside the circle.
We have,
To determine the location of point N(-5, -3) in relation to the given circle centered at C(0, 0), we can calculate the distance between point C and point N.
- If the distance is equal to the radius of the circle, then N lies on the circle.
- If the distance is greater than the radius, N lies outside the circle.
- If it is smaller, N lies inside the circle.
Let's calculate the distance between C(0, 0) and N(-5, -3):
Distance = √[(x2 - x1)² + (y2 - y1)²]
= √[(-5 - 0)² + (-3 - 0)²]
= √[25 + 9]
= √34
Since the distance (√34) is less than the radius of the circle, which is √38 (distance between C and M), we can conclude that the point N(-5, -3) lies inside the circle centered at C(0, 0).
Thus,
Point N(-5, -3) lies inside the circle.
