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."

Answer:
Step-by-step explanation:
add each number together
each of them should equal 88
then divide it by how many numbers there are. So it's 8.
this equals 11
18 - h = 13 when h = -5
18 - (-5) = 13
18 + 5 = 13
23 = 13
False, h would need to equal +5
Hope this helps! ;)
