Width = x then length = 2x
2x * x = 18
x^2 = 18/2 = 9
x = 3
So the width = 3 feet and the length = 6 feet.
36 erasers shared in the ratio 6 is 6 (36/6)
So the is 6 in 1 ratio.
6 x the ratio 2 is 12
So there are 12 pencils
If you would like to solve 16x^2 - 81 = 0, you can calculate this using the following steps:
<span>16x^2 - 81 = 0
</span>(4x - 9) * (4x + 9) = 0
1. 4x - 9 = 0 ... 4x = 9 ... x = 9/4
2. 4x + 9 = 0 ... 4x = - 9 ... x = - 9/4
The correct result would be: <span>x = 9 over 4, x = −9 over 4.</span>
The answer is x=2/3!! Hope this helped
