Answer:
44 square units
Step-by-step explanation:
The area of a trapezoid with bases b₁ and b₂ and height h is given by the formula

If you're wondering how we get this formula, check the attached illustration (remember the area of a parallelogram is its base multiplied by its height)! Moving on to our trapezoid, the pairs of points (-5,-3)(4,-3) and (6,-7)(-7,-7) form two horizontal segments, which form b₁ and b₂, and our height is the distance between the y-coordinates -3 and -7, which is 4. We can find b₁ and b₂ by finding the distance between the x coordinates in their pairs of points:

Putting it altogether:

So the area of our trapezoid is 44.
Answer:
x=-2, y=8. (-2, 8).
Step-by-step explanation:
8x+5y=24
y=-4x
----------------
8x+5(-4x)=24
8x-20x=24
-12x=24
x=24/-12
x=-2
y=-4(-2)=8
280 * 0.6 = 168
168 is the amount it cost the store to buy the coat.
168 * 0.7 = 117.60
it would cost an employee 117.60 to purchase the coat at the sale
The answer would be 120 hope this helps!!
