Answer:

Step-by-step explanation:

To find the area of a rectangle you use the formula: A= lw

** l is length and w is width

For figure A and C, they're rectangles, so you multiply the length and the width to get the area:

Fig. A )A=lw

= (4)(4)

= 16

For figures B and D, you use the formula: A= bh/2

**B is the base and h is the height

Fig. D) A=bh/2

= 6(4)/2

= 12

N/5 - 9n/10 = 1/5 What does n equal ?

miskamm [114]

$\frac{n}{5} - \frac{9n}{10} = \frac{1}{5}$

$\frac{n}{5}* \frac{2}{2}- \frac{9n}{10} = \frac{1}{5}$

$\frac{2n}{10}- \frac{9n}{10} = \frac{1}{5}$

$\frac{-7n}{10} = \frac{1}{5}$ (multiply each side by 10)

-7n = 1/5 * 10

-7n = 10/5

-7n = 2 (divide eaach side by -7)

n = 2/-7

$n =- \frac{2}{7} \ \textless \ -answer$ (or about -0.286)
