Answer:
C
Step-by-step explanation:
sqrt x can be zero, but you can't sqrt a negative number. there is no further restrictions on sqrt x, there it goes to positive infinity.
-x+7 (5x-3)=-21
-x+35x-21=-21
34x-21=-21
34x=0
The answer to find x or y is not possible
You would distribute the 72 to the twenty-four getting 120.
5(x)=10x+8 so x is equal to -3
I believe your answer is D. 77.
