The two rectangles are similar. What is
the length of x?

x = 5

Step-by-step explanation:

The two rectangles are similar. What is

the length of x?

For the bigger rectangle

Length = 5

Width = 5

For the smaller rectangle

Length = x

Width = 5

We find x using Proportion

Width/Length

= 5/5 = 5/x

Cross Multiply

5x = 5 × 5

x = 25/5

x = 5

yes

step-by-step explanation:

so of course you want to start by plugging the 5 in which goes to 7(5)+3(5)=50 because 7*5=35 and 3*5=15 and then add them together, then plug in the 5 to the other equation as well 9(5)+5=50 because 9*5= 45 and then add 5 and so yes they are equivalent.
