I have been stuck on number 10 (this problem) for a while now. Can anyone help me with it and walk me through every step in orde
r to get a correct answer for the math problem in the picture? Thanks!! I’ll be giving away as many points as I can for a response! It must follow the criteria listed above though. Help and steps.
When you multiply a same number but with different powers, you can simply add the powers together. So, in your question, add the powers -1 and -7 together. 7^(-1) x 7^(-7) = 7^(-8)
When you divide a same number but with different powers, you subtract the power at the top with the power from the denominator. So, -8 - (-7) = -1. 7^(-8) / 7^(-7) = 7^(-1)
So your answer would be 7^(-1). Hopefully my explanation was clear?
The length is 9 feet. The formula for Area is A= L*W*H. You are given A=189, W= 7 feet and H= 3 feet. Solve formula for L. 189= L*7* 3 189=21 L Divide both sides by 21 to solve for L 189/21 = 21L/21 9=L
