Answer:
x < −8
Step-by-step explanation:
Let's solve your inequality step-by-step.
<u>Step 1</u>: Simplify both sides of the inequality.
<u>Step 2</u>: Add 9 to both sides.
<u>Step 3</u>: Divide both sides by -3.
-3x 24

-3 -3
x < -8
<u>Answer:</u>
x < −8
Answer:
width = 7 and length = 9
Step-by-step explanation:
Let's assume width = w, and length = 2 + w
So area of a rectangle = width * length
63 ft² = w (2 + w)
63 = 2w + w²
w² + 2w - 63 = 0
Use the quadratic formula to solve this
here, a = 1, b = 2 and c = -63
w = 7 or -9
The dimensions of a rectangle cannot be negative. So we take the dimension, w = 7.
Width = 7 and Length = 7+2 = 9
