Answer:

Step-by-step explanation:
To solve a formula for one of its variables do that
- Separate it on one side and the other terms on the other side
- Make its coefficient equals 1
Let us use these steps to solve our question
∵ V =
b²h
→ Underline b
∴ V =
<u>b²</u>h
→ Multiply both sides by 3 to cancel the denominator on the right side
∴ 3V = <u>b²</u>h
→ Divide both sides by h to move it to the other side
∴ 
→ To find b take √ for both sides
∴ 
→ The square root will cancel the power 2 of b
∴ 
→ Switch the two sides
∴ 
Answer:
The answer is 6 because 3(6) = 18, which can be written as 3 x 6 = 18
Answer:
√16
Step-by-step explanation:
√15=√(3·5)
√16=√4²=4
√21=√(3·7)
√22=√(2·11)
Answer:
Step-by-step explanation:
A.) As the number of hours spent on homework increases, the test scores received also most likely will increase.
B.) If someone does 2 hours of homework, you just sub in 2 for x, so you should get the equation y=8(2)+40, or a score of 56.
C.) The 40 is the y intercept, which means that the student is guaranteed to get at least a 40 on a test even if they study for 0 hours.
Hope this helps :)
