A trapezoid is a 4-sided figure with one pair of
parallel
sides. For example, in the diagram to the right, the bases are parallel. To find the area of a trapezoid,
take the sum of its bases, multiply the sum by the height of the
trapezoid, and then divide the result by 2, The formula for the area of a trapezoid is:

Answer:
x = 8
Step-by-step explanation:
3/4x - 7 = -1
Your first step is to isolate the variable term 3/4x, to do this you have to add 7 to both sides:
3/4x -7 (+7) = -1 (+7)
3/4x = 6
Next, you want to get rid of the fraction by multiplying both sides by the denominator #, 4
3/4(x4) x = 6(x4)
3x = 24
Final step, you divide by three to isolate the x!
3x/3 = 24/3
x = 8
Hope this helps! =D
