A trapezoid has an area of 150 square meters. If the bases are 14 meters and 16 meters, what us the height of the trapezoid?
goldenfox [79]
To find the area of a trapezoid, we use the following formula:
a = \frac{1}{2} (b1 + b2) \times h
In this formula a represents the area and b1 and b2 each represent a base of the trapezoid.

So, we have got the following information
a = 150
b1 = 14
b2 = 16

Filling in the formula gives us:
150 = \frac{{1} }{2} \times (14 + 16) \times h
150 = \frac{1}{2} \times 30 \times h
150 = 15 \times h
Finally we have to divide both sides by 15.
h = 150 \div 15 = 10
Therefore, the height of the trapezoid is 10 meters.

2x^3-16x^2-40x=0 factor
ExtremeBDS [4]

The given expression is

2x^3-16x^2-40x=0

We extract the common factor 2x.

\begin{gathered} 2x(x^2-8x-20)=0 \\ 2x=0\rightarrow x=0 \\ x^2-8x-20=0 \end{gathered}

The first solution is 0.

Now, we solve the quadratic expression. We have to find two numbers whose product 20 and whose difference is 8. Those numbers are 10 and 2.

x^2-8x-20=(x-10)(x+2)<h2>Hence, the given expressions expressed, as factors, is</h2>2x^3-16x^2-40x=x(x-10)(x+2)
