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:
- 24x + 9
Step-by-step explanation:
Differentiate each term using the power rule
( a
) = na
Given
f(x) = - 12x² + 9x, then
f'(x) = (2 × - 12)x + (9 × 1) 
= - 24x + 9
Answer:
A
Step-by-step explanation:
By vertical line test, if you draw any vertical line, except for A, all graph meet at more than two points. So, graph A represents y as a function of x.
