To evaluate the expressions, you substitute -9 for x and 3 for y into the expressions
(4y)^2 - (2x)
= (4(3))^2 - (2(-9))
= (12)^2 - (-18)
= 144 + 18
= 162
4y^2 - 2x^2
= 4(3)^2 - 2(-9)^2
= 4(9) - 2(81)
= 36 - 162 = -126
Answer:product * . . . x is 3/4 as many as y x = (3/4)y. So, "3/4 as many oranges as apples" means. "number of oranges is 3/4 number of apples"
