▹ Answer
<em>(w = 7, w = 8/5)</em>
<em></em>
▹ Step-by-Step Explanation
(7 - w)(5w - 8) = 0
Separate:
7 - w = 0
5w - 8 = 0
Solve:
w = 7
5w - 8 = 0
(w = 7, w = 8/5)
Hope this helps!

Let L be length and W be width.
L = 2W
And our perimeter is 2L + 2W. Substitute L to get:
2*(2W) + 2W = 24
4W + 2W = 24
6W = 24
W = 4
That means L equals 8.
So our area of the rectangle is L*W or 8*4 = 32 units squared
Since we know a = 3, substitute this into the expression:
2a² = 2 x 3²
3² = 9
So 2a² = 2 x 9
2a² = 18
We know b = 2 and c = 1, so substitute these values into the expression:
3b² - c³ = 3 x 2² - 1³
2² = 4
1³ = 1
So:
3 x 4 - 1
Using the order of operations we multiply first:
3 x 4 = 12
Take off the 1:
Final answer:
3b² - c³ = 11
