Aye bro. That’s good and all, but ain’t no one gonna read that paragraph. Thanks for the points though
Answer:
9 and 14
Step-by-step explanation:
We know that the perimeter is equal to:
P = 2l + 2w = 46
If we divide by 2, we are left with:
l + w = 23
I = 23 - w
Now the area is equal to:
A = l * w = 126
l * w = 126
Now replacing it, we are left with:
(23 - w) * (w) = 126
(-w ^ 2) + 23 * w = 126
Rearranging:
w ^ 2 + -23 * w + 126 = 0
We factor and we have:
(w - 9) * (w - 14) = 0
w - 9 = 0 => w = 9
w - 14 = 0 => 2 = 14
If w = 9, l = 23 - 9 = 14
If w = 14, l = 23-14 = 9
So the dimensions are 9 and 14.
0.32 x 10^2 would be 32, in any case you have a positive exponent on the 10, the decimal to the left and in this case it would be moved two places to the left, equaling to 32.
0.32 x 10^2 = 3.2 = 32.
if this was a negative 2 it would be moved 2 places to the right.
0.32 x 10^2 = 0.0032
Answer:
6x^2 + 8x + 28
Step-by-step explanation:
2 times the length plus 2 times the width gives the perimeter
2(3x^2 + 3x + 6) + 2(x + 8)
6x^2 + 6x + 12 + 2x + 16
6x^2 + 8x + 28
