Step-by-step explanation:
The area (A) of a rectangle is calculated as
A = width × length
let width be w then length is 2w + 3 ( 3 more than twice the width ), then
A = w(2w + 3) ← distribute
= 2w² + 3w
When w = 4 , then
A = 2(4)² + 3(4)
= 2(16) + 12
= 32 + 12
= 44 ft²
<u> 4 x² = 64</u>
Divide each side by 4 : x² = 16
Take the square root
of each side: x = √16
x = <em>+ 4</em>
and
x = <em>- 4</em> .

Hey You!
Let's solve this step-by-step:
9.99 * 20% = 1.998
9.99 - 1.998 = 7.992
7.992 * 6.75% = 0.53946
7.992 + 0.53946 = 8.53746
The total cost of his order is $8.53
