4x-8 = 31
4x = 31 + 8
4x = 39
x = 9.75
Answer:
C
Step-by-step explanation:
When you are given any number to an exponent, you need to multiply it by itself as many times as the exponent's number. For example, if you got 4^7, you would multiply 4 * 4 * 4 * 4 * 4 * 4 *4 for a total of 7 times. In this case, it is 1/2 * 1/2 * 1/2 because the exponent is 3, meaning you do that 3 times.
Answer:
No

The volume of the regular pyramid is 128 unit³.
Option D) 128 unit³ is the correct answer.
This question is incomplete, the missing image is uploaded along this answer below.
<h3>What is the volume of the regular pyramid?</h3>
The volume of pyramid is expressed as;
V = ( 1/3 ) × l × w × h
Given that;
- Length l = 8
- Width W = 8
- Height h = 6
We substitute our given values into the equation above.
V = ( 1/3 ) × 8 × 8 × 6
V = 128 unit³
The volume of the regular pyramid is 128 unit³.
Option D) 128 unit³ is the correct answer.
