Answer: 4x³+29x²+40x-48
Step-by-step explanation:
The product of two functions=f(x)·g(x)=fg(x)
Use FOIL method to simplify expression.
f(x)·g(x)
=(4x²+13x-12)·(x+4)
=4x³+16x²+13x²+52x-12x-48
=4x³+29x²+40x-48
Answer: 4x³+29x²+40x-48
Step-by-step explanation:
To solve f(x)·g(x), you multiply them together.
(4x²+13x-12)(x+4) [distribute by FOIL]
4x³+16x²+13x²+52x-12x-48 [combine like terms]
4x³+29x²+40x-48
Now, we know that f(x)·g(x)=4x³+29x²+40x-48.

Answer:
Perimeter = 40 inches
Step-by-step explanation:
Length = 16 inches
Width = 25% of length (16)
= 25% of 16
25% = 1/4
Width = 1/4 x 16
= 4 inches
Length = 16 inches
Width = 4 inches
Perimeter of a rectangle = length + length + width + width:
= 16 + 16 + 4 + 4
= 32 + 8
= 40
PERIMETER = 40 inches
So glad I could help :)
