Option B: The area of the trapezoid is 157.5 m²
Explanation:
We need to determine the area of the trapezoid.
The area of the trapezoid can be determined by the formula,

where h is the height, a and b are the base of the trapezoid.
From the figure, it is obvious that
,
and 
Substituting these values in the formula, we have,

Simplifying the terms, we have,

Multiplying the terms in the numerator, we have,

Dividing, we get,

Thus, the area of the trapezoid is 157.5 m²
Hence, Option B is the correct answer.

Answer:
52 measures
Step-by-step explanation:
Let s represent the length of the second song. Then the first song's length is 108 -s, and the difference in length is ...
(108 -s) -(s) = 4
108 -2s = 4 . . . .collect terms
54 -s = 2 . . . . divide by 2
52 = s . . . . . add s-2
Grace's second song is 52 measures long.
Answer:
I think it would be dream shopping if you are good at math. If you are bad it's a real nightmare. At least that's what I think
To solve the equation, it is necessary to isolate the unknown variable "x" first. This is done as shown below:
2x - 3 = 15
Adding 3 to both sides of the equation:
2x - 3 + 3 = 15 + 3
2x = 18
Dividing 2 from both sides:
2x/2 = 18/2
x = 9
Among the choices, the correct answer is B.
