Answer:
y = -9
Step-by-step explanation:
Honestly sad to say, but I didn’t pay attention to this part of school so rip you bud
Part a.
<span>The perimeter formula is: </span>
P = 2w + 2LYour answer for part A is
P = 2w + 2LPart b.
They tell us in part b, that:
w = 6L + 20
Substitute that into what we got for part a.
P = 2(6L + 20) + 2L
P = 12L + 40 + 2L
P = 14L + 40Your answer for partb is
P = 14L + 40Part c.
So we take what we got from part b, and solve for L.
P = 14L + 40
14L = P - 40

That is your answer for part 3 ^
part d.
Plug in w = 32 into what we first got in part b.
w = 6L + 20
32 = 6L + 20
6L = 12
L = 2Your answer for part d is
L = 2<span>:D</span>
Ill only answer the first 2 question since its only 6 points....
A. (21,3),(12,6)
B. -1/3
Work:
6-3/12-21
-3/9
-1/3
Hope this helps out
The product using exponents would be -2^3= -8
