Answer:
7.1ft
Step-by-step explanation:
The formula for calculating the total surface area of a cube is 2(L²+L²+L²)
=2(3L²)
= 6L²
Where L is the length of the cube
If the total surface area of a cube is 302.46ft², then
302.46 = 6L²
L² = 302.46/6
L² = 50.41
L =√50.41
L = 7.1ft
The length of the side of the cube is 7.1ft
( - 45, 0)
to find the x-intercept let y = 0 in the equation
x = 0 →
x = - 15
multiply both sides by 3
x = 3 × - 15 = - 45
x-intercept = ( - 45, 0)
The first error was made in step 1
The correct quotient should be 31
Explanation: I sent a picture below showing how to do long divison, I was not able to do it on paper, sorry.
I hope this helps!
If you add them all together, you'd get 157. Then you divide by 7 and you'd get 31.4
