Answer:

Area of a trapezoid = ½(a + b)h, where a and b are the lengths of the parallel sides and h is its height. 

From your information 20 = ½(2z + 3 + 6z – 1)z = ½(8z + 2)z = z(4z + 1) 

Solve 20 = 4z² + z which is 0 = 4z² + z – 20 using the quadratic formula

Answer:

d) 10

Step-by-step explanation:

x ÷ \frac{1}{2}  + 8 = 13

substitute 10 for x:

⇒ 10 ÷ \frac{1}{2}  + 8 = 13

solve:

1) divide 10 by \frac{1}{2}

⇒ 10 ÷ \frac{1}{2}  = 5

2) add 8 to 5

⇒ 8 + 5 = 13
