Answer:
P = 8h+ 38
A = 3h^2 + 35h+88
Step-by-step explanation:
P = 2(l+w)
P = 2(3h+11+ h+8)
combine like terms
P = 2(4h+19)
distribute
P = 8h+ 38
A = l*w
A = (3h+11) * (h+8)
FOIL
3h*h + 3h*8 + 11*h + 8*11
3h^3 + 24h + 11h + 88
3h^2 + 35h+88
Answer:
3.5*10^-3
Step-by-step explanation:
86 × π = 86π
or
86 × 3.14 = 270.04
you can use both of them depends on what form the question is asking that ur answer be in
