Answer:

Original rectangle: Since the area of a rectangle is the length * width, the area of this rectangle is 7 * 2 = 14 square cm.

New rectangle: The new dimensions of this are 7*3 = 21 cm by 2*3 = 6 cm. To find the area, we multiply these two together. 21*6 = 126 square cm.

126 is 9 times greater than 14, so the area will be multiplied by 9.

If y=1.8 when x=-0.18 what is y when x= 0.51

GaryK [48]

You can set it as a proportion:

$\frac{x_1}{y_1} = \frac{x_2}{y_2}$

$\frac{-0.18}{1.8} = \frac{0.51}{y_2}$

Cross multiply:

-0.18y = 0.918

Divide:

y = -5.1
