PLEASE HELP ASAP Given: Quadrilateral PQRS is a rectangle Prove: PR = QS What is the reason for the third step in this proof? A: Corresponding sides of congruent triangles are equal in length. B: The diagonals of a rectangle bisect each other. C: SSS criterion for congruence. D: Opposite sides of a parallelogram are congruent.

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8

yx = 36

step-by-step explanation:

cos f = opposite side/ hypotenuse

cos f = yw / yx

we know cos f = 4/9 and yw =16

4/9 = 16/yx

multiply each side by yx

4/9 yx = 16/ yx * yx

4/9 yx = 16

multiply each side by 9/4

9/4 * 4/9 yx = 16 *9/4

yx = 36

all you should have to do is insert 1 where the c is, representing that one car is sold.

f(c) = 250c + 500

f(1) = 250(1) + 500

f(1) = 250 + 500

f(1) = 750

he earns $750 for each car sold.

hope this you! have a happy , here's a turkey!
