Answer:

8 feet

Step-by-step explanation:

Let l and w be length and width, respectively. Then:

lw=144 and

l=w+10

So:

w(w+10)=144

w²+10w-144=0

(w+18)(w-8)=0

w=8 as the width ................

Answer:

AN = 16 units

Step-by-step explanation:

So we can use the fact that $\frac{AN}{FN} =\frac{OR}{FR}$

Since this is an isosceles triangle, segments FO and FR are both equal to 7

Manipulating the equation above to solve for AN we have $AN = \frac{(FN)(OR)}{FR}$

Substituting in the known values we have $AN=\frac{(10)(11.2)}{7} =16$

The answer and how to do it.

Kruka [31]

let x = orginal price of the shorts

$21 = x(100%-20%) * 1.05

$21 = x(80%) * 1.05

$21 = 0.8x * 1.05

Subtract 1.05 from both sides

$19.95 = 0.8x

Divide 0.8 from both sides

$24.9375 = x

So the orginal price of the shorts are about $24.94
