Answer: The width is + 1x -4
Step-by-step explanation:
We know to find the perimeter we have to add the distance around the rectangle.The distance can also be sought as 2 times the length plus times the width.
So as a formula is like P = 2l + 2w where P is the perimeter.
We are given the perimeter so we can plot it into the formula and also plot in the length because it says the length is 3x -1
+8x - 10 = 2(3x -1) + 2w Now we have to solve for w .Break it down
( + 8x -10) = (6x -2 )+ 2w subtract 6x - 2 from both sides
( + 8x -10) - (6x -2) = 2w
( + 2x -8) = 2w now divide both sides by 2
One the left side factor the numerator
= w Now multiply both sides by 2
w =( + 1x-4 )
The width is x^2 + 1x -4
The answer to your question is 106
3(4x - 7y = 28)
-2(6x - 5y = 31)
12x - 21y = 84
<u>-12x + 10y = -62
</u> 0 - 11 y = 22
<u>
</u>y = 22/-11
y = -2
12x - 21y = 84
12x - 21(-2) = 84
12x + 42 = 84
12x = 84 - 42
12x = 42
x = 42/12
x = 3.5
