Maya is said to be m years old now. We are asked what will be her age after four years from now so we just have to add 4 years from her age now. The correct expression to calculate her age should be m+4. This cannot be seen among the choices given above.
First is to get the given data that we might be able to use for computation.
H = 8 inches
Area = 96
B1 = B1
B2 = B1+6
Next is to know the area of a trapezoid
Area = H x (B1 + B2)/2
96 = 8 x (B1 + B1 + 6) / 2
96 = 8 x (2B1 + 6) /2
96 = 4 x (2B1 + 6)
14 = 2B1 + 6
2B1 = 8
B1 = 4
B2 = 10
Greatest common factor is 2. Divide both terms by 2 and you get:
4(2z +1)
By multiplying the factors together you’ll get 6
