Incorrect, she should have divided both sides by 8. The answer should be x=7. There is only 1 solution to the equation because x is raised to the first degree. It is not a polynomial equation so there won't be more than 1 answer to the equation.
Answer:
3 7/8
Step-by-step explanation:
A= 50.27 because the formula is pi times radius squared
C= 24.13 because the formula is 2 times pi times radius
16*28=448
28 is 12 inches higher than 16 so it should work.
8r+(12-3)p-7------>8r+9p-7
