8+3(5-1) =20 I am very confused on how this equals 20, someone please explain. thanks
soldier1979 [14.2K]

Step-by-step explanation:

first you have to do the subtraction in the parentheses so it's 8+3(4) and then you multiply the 3 by 4 (only the 3 because the 8 isn't next to the multiply) and then you have 12, add 8 and it's 20

A cube has side length x. One side of the cube is increased by 4 inches, and another side is doubled. The volume of the new rect
AfilCa [17]

Let

x-------> the length side  of the original cube

we have

2x^{3} +8x=450\\2x^{3}=450-8x

Divide by 2 both sides

x^{3}=225-4x

The system of equations is equal to

y=x^{3} --------> equation 1

y=225-4x --------> equation 2

using a graphing tool

see the attached figure  

we know that

the solution of the system of equations is the intersection both graphs

therefore

the solution is

x=5.86\ in

therefore

<u>the answer is</u>

5.86\ inches
