So the Rational Zeros Theorem states that <u>the potential zeros are ± P/Q, with P = factors of the constant and Q = factors of the leading coefficient.</u>
In this case, the constant is -3 and the leading coefficient is 2.
- P = 1,3
- Q = 1,2
With P and Q established, divide them all as such:
<u>In short, your potential zeros are ± 1/2, ± 3/2, ± 1, and ± 2.</u>
The area of a trapezoid is:
A = area
a = base 1
b = base 2
h = height
Area = unknown
base 1 = 2.5
base 2 = 7.5
height = 2.5
^^^Plug these numbers into the formula!
A = (10/2)(2.5)
A = (5)(2.5)
A = 12.5
Hope this helped!
