L= 2w+30
Perimeter= 2(l+w)
Substitute in the length above
P=2 ((2w+30) + w)
Remember order of operations. You must multiply everything by 2 before adding.
P=4w+60+2w
P=6w+60
Answer:
like fractions have the same denominator. So A is correct
Answer:
there's nothing here to answer
Answer:
2w^2 -7w-2
Step-by-step explanation:
(4w^2 – 4w – 8) – (2w^2 + 3w – 6)
Distribute the minus sign
(4w^2 – 4w – 8) – 2w^2 - 3w + 6
I like to line them up vertically
4w^2 – 4w – 8
– 2w^2 - 3w + 6
-----------------------------
2w^2 -7w-2
