36 pounds because there’s already 36 pounds in the tire and there needs to be 72
<span>Let l equal the length of the rectangle
</span><span>width of a rectangle is 10 mm shorter than its length
</span>
<span>a. Write an expression for the width in terms of the length?
</span> w = l - 10
<span>b. Write an equation for the perimeter in terms of l.
P = l + l + (l-10) + (l-10)
P =4l - 20
</span><span>c. Solve the equation, clearly indicating the length of the rectangle.
</span> P =4l - 20
244 = 4l - 20
4l = 244 + 20
4l = 264
l = 284/4
l = 66
<span>d. Solve for the width of the rectangle. Clearly indicate the width of the rectangle.
</span>w = l - 10
w = 66 - 10
w = 56

Answer:
lines 1 and 3
Step-by-step explanation:
y = 2 is a horizontal line parallel to the x- axis
x = - 4 is a vertical line parallel to the y- axis
Then these 2 lines are perpendicular to each other
y = 15x - 3 ( in the form y = mx + c ) with m = 15
y + 1 = - 5(x + 2) ( in the form y - b = m(x - a) with m = - 5
For the lines to be perpendicular the product of their slopes = - 1
However
15 × - 5 = - 75 ≠ - 1
The 2 lines 1 and 3 are perpendicular
