What is the value of (f +2g)(4) f(x)= (x-2)²; g(x)= x+3

18.

Step-by-step explanation:

g(x) = x + 3 so 2g(x) = 2x + 6

(f + 2g)(x) = (x - 2)^2 + 2x + 6

therefore

(f + 2)(4) = (4 - 2)^2 + 2(4) + 6

= 2^2 + 8 + 6= 18.

area = length x width

length = 2 x width

32 = 2 x width x width

32 = 2 x width^2

36 = width ^2  

width = 6

length = 12

area is 32

perimeter = 2 x 12 + 2 x 6 = 24 + 12 = 36
