B. 10 and 11
This is because 10x10 is 100, so thats less than what you need and then 11x11 is 121, and that is more than you need... So it would be between 10 and 11.
First step of the equation is to simplify the equation 2a • b = a2 + b2 into 2 ab = a2 + b2. This cannot be factored anymore although. when we try to substitute a with 5 and b with 2, the answer in the right hand side of the equation is -9. hence the answer to this problem is false. we can try another values to verify.
The first step u should do is (3+2)
Answer:
x=6
Step-by-step explanation:
3x+(-10)=8
3x-10=8
-10+10=0
8+10=18
3x=18
3x/3=x
18/3=6
x=6
