Answer:

Step-by-step explanation:
I attached an image to aid the understanding of the question.
Looking at the image, we see that the 8 shaded parts are congruent, as affirmed in the question as well. And we are told that T = 3, this implies that the area of the square with T as it's side is 9ft². Since all the 8 squares are congruenrt, it means each square has its area to be 9. Therefore, the total area of the 8 shaded squares will be:

It remains the area of the shaded square with side S.
From the question, we have the following ratio:
I did not add ± because length is always positive, so the case of negative is eliminated.
Now the areas of S is 
Therefore, the total area of the shaded squares is

Answer:
PQ = 18
Step-by-step explanation:
If R is the midpoint of PQ, then PR = RQ
⇒ 6x + 7 = 3x + 8
⇒ 3x = 1
⇒ x = 1/3
So PR = 6x + 7 = 6(1/3) + 7 = 9
and RQ = 3x + 8 = 3(1/3) + 8 = 9
⇒ PQ = PR + RQ = 9 + 9 = 18
Answer:

Step-by-step explanation:
-------------------------
Given:

---------->>>>
Combine like terms.

---------->>>>
Add 12 to both sides.

---------->>>>
Divide both sides by 9.
