Divide the 3 from the 3c, and move over towards the 3 on the right side of the equation. 3 ÷ 3 = 1, so c = 1.
Answer:
4.5 or 4 1/2
Step-by-step explanation:
First, you multiply 3 * 3
Second, you divide 9 / 2 = 4.5
Lastly, have a beautiful day! :)
Let the width be x
Length= x+7
Area=lw
99=(x+7)(x)
99=x²+7x
0=x²+7x-99
x= -14.04 or x=7.04
Since a length cannot be negative, the width is 7.04 ft and the length (7.04+7)=14.07 ft
Hope I helped :)
