Area of a square = Side × Side
Side = 7x-3
Area of the square = (7x-3) × (7x-3)
= 7x(7x-3) -3(7x-3)
= 49x^2 -21x -21x +9
=49x^2 -42x +9
I don't know how to set up a diagram for this, but I could write an expression. 20*4= x
sorry, but I hope this helps. I not even sure my expression is correct.
Answer:
3 1/3
Step-by-step explanation:
Multiply
2 1/2 * 1 1/3 = 20/6

(15, -8) :)
From C to midpoint you do (+10, -7), so you have to do that again to get to D
