Answer:
10
Step-by-step explanation:
Let the width length be x.
Width length = x
Length = 2x + 4
Perimeter = width + length + width + length
= x + 2x + 4 + x + 2x + 4
= 6x + 8
6x + 8 = 28
6x = 28 - 8
= 20
x = 20 ÷ 6
x = 3
Length (2x + 4) = 2(3
) + 4
= 6
+ 4
= 10
Answer: Two can be factored from each term in the trinomial to generate 2( x 2 + 6 x + 9), and no.

Answer:
h(3) = 207 feet
Step-by-step explanation:
what is the maximum height for -16t^2+96t+63
h(t) = -16t^2+96t+63
We see max height at the vertex of this parabolic function
x = -96/2*(-16) = 3 seconds
h(3) = -16*3*3 + 96*3 + 63
h(3) = -144 + 288 + 63
h(3) = 207 feet
Answer:

Step-by-step explanation:
1) regroup term.

2) Simplify 1/2 ( 8x - 4 ) to 8x - 4/2.

3) Factor out the common term 4.

4) Simplify 4( 2x - 1 ) / 2 to 2( 2x - 1).

5) Expand by distributing terms.

6) Remove parentheses.

6) Collect like terms.

8) Simplify.
