Answer:
x = 8.4
Step-by-step explanation:
The area of a rectangle is equal to the length times the width.
126 = 5x * 3x
126 = 15x
8.4 = x
Since the side length of the square is equal to x, it is equal to 8.4.

First, we must fill in the missing numbers.
9*21 + (3*3)21 + 12
Start in the parentheses.
(3*3)21 = 9*21 = 189
189+189+12
The rest is just addition now!
189+189+12=390
390 is the correct answer.
