Answer:
5
Step-by-step explanation:
Simplifying
8 + 4 = 2(x + 1)
Combine like terms: 8 + 4 = 12
12 = 2(x + 1)
Reorder the terms:
12 = 2(1 + x)
12 = (1 * 2 + x * 2)
12 = (2 + 2x)
Solving
12 = 2 + 2x
Solving for variable 'x'.
Move all terms containing x to the left, and all other terms to the right.
Add '-2x' to each side of the equation.
12 + -2x = 2 + 2x + -2x
Combine like terms: 2x + -2x = 0
12 + -2x = 2 + 0
12 + -2x = 2
Add '-12' to each side of the equation.
12 + -12 + -2x = 2 + -12
Combine like terms: 12 + -12 = 0
0 + -2x = 2 + -12
-2x = 2 + -12
Combine like terms: 2 + -12 = -10
-2x = -10
Divide each side by '-2'.
x = 5
Simplifying
x = 5

Answer:
Increases 64 times
Step-by-step explanation:
The volume of the box can be calculated using formula

where
V = volume,
l = length,
w = width,
h = height
If the length was 0.3 inches, then the volume was

When the length became 1.2 inches, then all dimensions became
times greater, then the volume was

The volume increases
times
