The area of the rectangle is 70 yd2. what is the formula that shows the length of side y?

70 + 10 = y

70 − 10 = y

10y = 70

10 + 10 − 5 − 5 − 70 = y

(70 − 10 × 2) ÷ 2 = y

60 2(x + 2) in the diagram, gef and hef are congruent. what is the value of x?

If the endpoints of the diameter of a circle are (8, 6) and (2,0), what is the standard form equation of the circle? a) (x + 5)2 + (y + 3)2 = 18 (x + 5)2 + (y + 3)2 = 3.72 (x - 5)2 + (y - 3)2 = 18 d) (x - 5)2 + (y - 3)2 = 32
