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:
The perimeter of the scale floor is 34 inches.
Step-by-step explanation:
To solve, we can set up fractions:
![\frac{21}{7}=\frac{30}{x}](https://tex.z-dn.net/?f=%5Cfrac%7B21%7D%7B7%7D%3D%5Cfrac%7B30%7D%7Bx%7D)
Cross multiply and you get:
21x = 210
Divide each side by 21:
x = 10
Since you are trying to find the perimeter of the floor, you can use this equation:
2w + 2l = p
Substitute to solve:
2 ( width = 10 )
2 ( length = 7 )
2 ( 7 ) + 2 ( 10 ) = p
14 + 20 = p
34 = p
Answer:
x=79
Step-by-step explanation:
22+2x=180
2x=180-22
2x=158
x=79
