Answer:
x=7
Step-by-step explanation:
Step 1: Subtract 4x from both sides.
x+30−4x=4x+9−4x
−3x+30=9
Step 2: Subtract 30 from both sides.
−3x+30−30=9−30
−3x=−21
Step 3: Divide both sides by -3.
−3x
−3
=
−21
−3

Answer:
Option D = 144
Step-by-step explanation:
First, you are not putting the expression correctly. I'm assuming you are mean to say (ab)². This is because if you want to multiply by 2, the 2 usually goes first like this 2ab. But it's not case, so, it should be as I said.
Now, let's replace the values for a and b into the expression:
(ab)² = (4 * 3)² = (12)² = (12*12) = 144
That's is why is option D.
