A
x = 11
B. x=21
C. X = 61
D. x=-11
E. X=-21
Answer:
x = 11, x = -11
Step-by-step explanation:
I know this is kind of late but the two previous answers were wrong.
We have x² = 121. To find x, we need to get rid of the exponent, and to do this, we can take the square root of both sides:
√x² = √121
x = √121
You might think that x = 11 but remember, x can be negative as well because you can square negative numbers. Basically, every real number has two square roots - a positive and a negative one. So, the answer isn't just x = 11, it's also x = -11 because (-11)² = 121 as well.

Answer:
43.25=7+(1.25t)
Step-by-step explanation:
43.25=7+(1.25t)
-7. -7
36.25=1.25t
and then divide both by 1.25
it is 29 minutes
Answer:
the correct answer is 1.25x + 7= 43.25
