Answer:
6m + 5
Step-by-step explanation:
To fond the area of a trapezoid, add the top and bottom together, divide that by 2, than multiply by the height.
Area = (8+12)/2 = 20/2 = 10
10 x 9 = 90 square centimeters.
<span>Simplifying
y = 20x + 500
Reorder the terms:
y = 500 + 20x
Solving
y = 500 + 20x
Solving for variable 'y'.
Move all terms containing y to the left, all other terms to the right.
Simplifying
y = 500 + 20x</span>

This will allow you to get a B score.
To solve find the medium by adding the values divided by 4, solve for the unknown of the final exam, with the minimum value equalling 80, this will give you 68.</span>
For the first one, to find the missing fraction, add the first two fractions and subtract that from the last fraction. For the second question, subtract the first two fractions then add that to the last fraction. Hope this helps.
