solve. the square root of t +9=16

Question

A. 5
B. 7
C. 25
D. 49

Answer 1

The correct answer is A. 5.

To solve this equation, first isolate the square root term:

√(t + 9) = 16
(t + 9) = 16^2
(t + 9) = 256
t = 256 - 9
t = 247

Now that we have solved for t, we can plug it back into the original equation and solve for the square root:

√(247 + 9) = √256
√256 = 16

Therefore, the square root of t + 9 is 16, so t = 247 and the correct answer is 5.
