Divide both length and width by the dialtion factor and that will be the dimensions of the new rectangle. 2.5714in by 3.4286in. Round as needed
Answer:
x = 40
Step-by-step explanation:
2x = 4x - 40 (recall properties of a parallelogram)
Solve for x
2x - 4x = 4x - 40 - 4x (subtraction property of equality)
-2x = -40
-2x/-2 = -40/-2 (division property of equality)
x = 20
12 + h - 5 + h + 20h
= h + h + 20h + 12 -5
= 22h + 7 (Ans: D)
