The formula for finding the surface area of a cube is A=6y^2 where y is the side length. we know a=96. so we just isolate y.
96/6= 6y^2 / 6
16=y^2
sqrt (16) = sqrt(y^2)
4=y
So y is 4
Answer:
7x^2+2x-4
Step-by-step explanation:
a standard form is ax+by=c
5x^2 add 2x^2=7x^2 then -2x but when you have a -10 +6 you get -4 giving you the answer of 7x^2 +2x -4
The correct option is (B) 4x^2 + 18x + 18
Explanation:
The area is given as:
(3+2x)(6+2x)
To find the polynomial just simplify it.
3(6+2x) + 2x(6+2x)
18 + 6x + 12x + 4x^2
4x^2 + 18x + 18
