Trapezoid Area = (Base1 + Base2) (h/2)
so A = (3x + 5x )(6x/2)= 24x^2
14 + x < = 3x....ur inequality
***
the sum means add....so the sum of a number and 14 is 14 + x
is less then or equal....< =
3 times the number....3x
To solve this, we combine like terms. Our equation becomes:
-2u + 13 = -5
Now to subtract both sides by 13 to find that:
-2u = -18
Finally, we divide both sides by the coefficient and find that:
u = 9
