2. 3x - 2
Answer:
vvvv
Step-by-step explanation:
1. Make it so 1/4 is an eighth so you can subtract it from 5/8.
1/4 x 2 = 2/8
2. Subtract 2/8 from 5/8.
5/8 - 2/8 = 3/8
Daniel ate 2/8s of the left over pie, and there is 3/8s remaining.
Answer:
(x + 1)² = (2x)²
(1 + 1)² = (2(1))²
2² = 2²
4 = 4
(-1 + 1)² = (2(-13))²
(-12)² = (-26)²
Not true
x = -13 satisfies neither
Answer:
A = 120 cm^2
Step-by-step explanation:
The formula for surface area of a rectangular prism is:
A = 2(area of the top) + 2(area of the front) + 2(area of one side)
Substituting the values:
A = 2(20) + 2(16) + 2(24)
First, distributing:
A = 40 + 32 + 48
Then adding, giving your final answer
A = 120 cm^2
Hope this helps you :)
