Answer:
5x+10
Step-by-step explanation:
3x+2x=5x
5x +10
it is a have a great day xoxoxoxoxoxo
P=2l+2w
100=2l+2w
divide both sides by 2
50=l+w
So what two numbers that have a sum of 50 have the largest product?
25*25=625 which makes for a large area, the largest
answer=l=25 w=25
Answer:
perimeter you add all sides together:
5x+2 +5x+2 +x +8 +x+8
12x +20
and for Area you multiply:
(x + 8)(5x + 2)
5x^2 + 2x + 40x +16
5x^2 +42x +16
so your answer is the first one or "A"
