2(32-3)^3
= 2(29) ^3
=78 ^ 3
= 78 times 78 times 78
= 42,588
Answer:
(f•g)(-5) = -238
Step-by-step explanation:
We have that:
f(x) = -3x + 2
g(x) = 4x + 6
Find (f•g)(-5).
First we find (f.g)(x)
So
f(x)*g(x) = (-3x + 2)*(4x + 6) = -12x² -10x + 12
When x = -5
-12(-5)² - 10(-5) + 12 = -238
(f•g)(-5) = -238
The rate in m³/m² is 40m³/m².
1 m³ is literally a cube with sides that are 1 m in length. 1 m = 100 cm, so each side of this cube is 100cm in length. Finding the volume means multiplying length by width by height:
100(100)(100)=1,000,000 cm³ in 1m³.
We know that we have 25,000cm³ of mulch; we divide to find how many cubic meters this is:
1,000,000/25,000 = 40 m³.
This makes the rate 40m³/m².
-3/2 is the factor would multiply the second equation to eliminate y.
The correct option is (C).
<h3>What is factor?</h3>
A number or algebraic expression that divides another number or expression evenly—i.e., with no remainder.
Given equation is :
9x+3/4 y =6
2x+1/2 y =9
If we have to eliminate the y variable so we have to multiply it by factor -3/2
Then the second equation become
-3/2(2x+1/2 y =9)
-3x- 3/4 y =- 27/2
As we can see the y variable of both the equation is same.
Hence, -3/2 is the factor would multiply the second equation to eliminate y.
