is h/[2(a+b)] or (h/2)(a+b)?

Answer 4

no, that's incorrect too

Answer 5

i'm asking you about the form of the question, try typing it using the "Equation", maybe it'll help us to understand the question correclty.

Answer 6

\[{\pi} = 3.14\]

Answer 11

P = 2L + 2W; for L

Answer 12

P = 2L + 2W
P - 2W = 2L
L = (P-2W)/2

Answer 13

thanks so much :)
