Answer:
Your teacher messed up the question so just put the top right answer and ask your teacher if they did accidently miss-type.
Step-by-step explanation:
The first thing to do in this equation is look at the exponents. When multiplying a variable (or any number equal to itself with the same exponent) you only have to add the exponent. So for a, you would add the exponents to get 0, so a to the power of 0 is 1, because any number to the power of 0 is 1. For b, we would add the 3 and 1. (When no exponenet is present in a number then it is 1, so for this I added 3 and 1). So it would be 4. The correct answer is
Answer:
30 = 9x + 7
Step-by-step explanation:
The total weight of the bundle = 30 pounds
The weight of the bricks = x pounds
But he carried 9 bricks = 9x pounds
He also carried additional 7 pounds of concrete block.
An equation to show the total weight he carried is
30 pounds = (9x + 7) pounds
Since 9x represents the total weight of the bricks he carried
7 represents the weight of the concrete block
And 30 pounds represents the total weight of everything he carried.

Answer:
area = 81π in² (or ≈ 254.47 in²)
Step-by-step explanation:
The formula for an area of a circle is area = πr².
You are given the diameter, which is 18 in.
diameter = radius (2)
So to get radius, divide the diameter in half:
18/2 = 9.
Now that we have the radius, put that back into the formula for the area of a circle:
area= π9²
Then, solve for the 9², which will be 81 and put it back into the formula.
area = 81π in²
If you need to get rid of the π, the answer will be about 254.47 in²
