The volume of the trapezoidal prism having side lengths x, (x+2), (x+4) and height of 2x is 2x³+6x² option first is correct.
<h3>What is volume?</h3>
It is defined as a three-dimensional space enclosed by an object or thing.
We know the volume of the trapezoidal prism can be given:

Where V = The volume of the trapezoidal prism:
Length of the trapezoid L = x
Top width a = (x+2)
Base width b = (x+4)
Height of the trapezoidal prism h = 2x


Thus, the volume of the trapezoidal prism is

X = (Probability of winning x winning amount) + (probability of losing x losing amount)
The amount she pays would be a negative value.
X = (0.05 * 140) + (0.98 * -9)
X = 7 + -8.82
X = -1.82
No because -4 is a negative number
