Answer:
Just round. sorry i dont know about the perimeter
Step-by-step explanation:
Answer : option B
Given
f(x) = x - 6
g(x)= √x (x + 3)
We need to find g(x) * f(x)
( x - 6) * (x + 3) √x
we use FOIL method to multiply (x-6)(x+3)
(
) * sqrt(x)
Now apply exponential property to multiply each terms with sqrt(x)
times sqrt(x) becomes \[sqrt(x^5)\]
-3x times sqrt(x) becomes \[-3sqrt(x^3)\]
-18 times sqrt(x) becomes -18sqrt(x)
So final answer is B
\[sqrt(x^5)\] - \[3sqrt(x^3)\]
-18sqrt(x)
Answer is 16X+9
because put an x chart and number 9 plus 8 is 16 +6+3 which is 9 so answer is 16x + 9
