Please help me by checking the following answers for me.

3. A student is attempting to solve the equation below for the variable x. Which of the statements below best applies to the mathematical work shown?

Given √(4x-6)=12, I square both sides, so (√4x)^2-6=〖12〗^2, or 4x -6 = 144. I can then solve for x, yielding x = 37 1/2 as my final answer.

A. The student did not correctly square both sides of the equation. - (This is my second answer.)

B. The student did not properly isolate the variable after squaring both sides of the equation.

C. The student omitted a negative solution to the equation.

D. The mathematical work is correct. - (I know it is not this because I got it wrong.)

4. Solve for x.

〖5x〗^2+3=-122

A. No solution. - (This is my second answer.)

B. -5 - (I know it is not the answer because I got it wrong.)

C. ±5

D. ±25

9. The acceleration of an object can be described by the equation a= 2d/t^2, where a is acceleration, d is the distance, and t is time. If an object accelerates at a rate of 2 m/s^2 for 10 meters, what is the total time elapsed?

A. 1/10 seconds - (This is my second answer.)

B. √(1/10) seconds

C. √10 seconds

D. 10 seconds - (I know it is not answer because I got it wrong.)

Please check them to see if I am correct. Any help will really be appreciated! :)
