Answer:
(f+g)(x)= 3x^2 -2x-1
Step-by-step explanation:
f(x) = -4x+3
g(x) = 3x^2+2x-4
(f+g)(x)= -4x+3 +3x^2+2x-4
Combine like terms
(f+g)(x)= 3x^2 -2x-1
Answer:
Length = 7cm, Width = 15cm
Step-by-step explanation:
Length = p
Width = 3(p-2)
= 3p-6
Perimeter = length + width + length + width
= p + 3p-6 + p + 3p-6
= 8p-12
8p - 12 = 44
Isolate 8p.
8p = 44+12
= 56
Find p.
p = 56 ÷ 8
p = 7
Length = 7cm
Width = 3(7)-6
= 21-6
= 15cm
