Answer:
x = 84 , y = 168
Step-by-step explanation:


Length x Width = Area
In your case, you'd want to flip around the equation.
100+x=900
900 divided by 100 is 9, so your width would be 9 Yards.
Answer:
16mm
Step-by-step explanation:
Just do 40 * 2/5 = 80/5 = 16mm
X² + 6 = 87
<u> - 6 - 6</u>
x² = 81
x = <u>+</u>9
x = 9 U x = -9
The solution set is equal to D. {<u>+</u>9}.
