Answer:
No, the following expression is not a difference of squares. Binomial can not be factored as the difference of two perfect squares. 3 is not a square.
Step-by-step explanation:
Factor
15x^2 - 25
(15x)^2(-5)^5
Divide by 3 and factor
5(3x^2-5)
"Theory:
A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)
Proof : (A+B) • (A-B) =
A2 - AB + BA - B2 =
A2 - AB + AB - B2 =
A2 - B2
Note : AB = BA is the commutative property of multiplication.
Note : - AB + AB equals zero and is therefore eliminated from the expression."
I put a picture to help u understand.
To find the X value of the solution, you would set the two equations equal to each other bu substitution:
if <span>y = -2x + 5 and y = 3x - 2,
</span>-2x + 5 must be equal to 3x - 2
solve for x... you should get 7/5
then, plug that into one of the original equations as X and you would get the Y value, 11/5
This point, (7/5,11/5) is where the two lines cross
If the factors of quadratic function f are (x – 7) and (x + 3). The solution of the quadratic function f will be the negative 3 and 7.
<h3>What is a factorization?</h3>
It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.
If the factors of quadratic function f are (x – 7) and (x + 3).
Then the zeroes of function f will be
(x – 7)(x + 3) = 0
x = 7, -3
Then the solution of the quadratic function f will be the negative 3 and 7.

Answer:
a: 0.1%
b. No it does not
c. Probably for safety reasons
Step-by-step explanation:
for women: z = (55.9 - 63.9)/3.6 = -2.22
The p-value for z = -2.22 is 0.0132, so only 1.32% of women could walk through without bending
for men: z = (55.9 - 69.7)/3.6 = -3.83
The p-value for z = -3.83 is 0.001, so only 0.1% of men could walk through without bending
