Answer:
21.90890230 or 21.91 (I'm assuming you're saying 120/ √30)
Step-by-step explanation:
I believe the right equation for determining the area of a trapezoid is as below,
A = h(a + b)/2
To determine the expression for b which is the length of one of its bases, we multiply the equation by 2.
2A = h(a + b)
Then, divide both sides of the equation by h,
2A/h = a + b
Then, subtract a from both sides of the equation,
2A/h - a = b
Lastly, interchange the sides of the equation to reveal the answer.
<em> </em>
<em> b = 2A/h - a </em>
Answer:
CB=18
And the measure of angle BDA is 21 degrees
Step-by-step explanation:
Answer:
The answer is B
Step-by-step explanation:
f(x) = 4x² + 1
g(x) = x² - 5
(f-g)(x) = 4x² + 1 - (x²-5)
= 4x² + 1 - x² + 5
= 3x² + 6
