Hello there!
The formula to find the area of a trapezoid is:
A =
Since we have everything, we just plug them in :)
A =
A = (3x+3x+4)/2 (x) + (3x+3x+4)/2 (2)
A= <span><span><span><span>3x^2</span>+<span>2x</span></span>+<span>6x</span></span>+<span>4
A = </span></span><span>3x^2+8x+4
The correct answer is option A
I hope I helped!
Please feel free to ask me any additional questions about the answer.

Answer: C. 5.8 inches
Step-by-step explanation:
The formula for calculating the Surface area of a cube is give as :
surface area = 6
Where a is the length of an edge
That is :
200 = 6
divide through by 6
200/6 =
that is
= 33.33333333
take the square root of both sides
a = 5.773502692
Therefore the length of an edge ≈ 5.8 inches

Step-by-step explanation:
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
In this question:
We want P(X = 4). So
