<h3><u>
The value of the number is equal to 16.</u></h3>
7x + 8 = 120
<em><u>Subtract 8 from both sides.</u></em>
7x = 112
<em><u>Divide both sides by 7.</u></em>
x = 16
Answer:
D
Step-by-step explanation:
Before the increase, the length is 6 and the width is 5, so the area is 5×6 = 30.
After the increase, the length is x+6, the width is x+5, and the area is tripled: 30×3 = 90.
Therefore:
(x+6) (x+5) = 90
the correct answer would be 36.156.
7.86
X 4.6
=36.156
