Hey there :)
f (x) = 5x² - 2x
g (x) = 3x² + x - 4
( f + g )( x ) is f ( x ) + g ( x )
5x² - 2x + 3x² + x - 4
Combine like-terms
5x² + 3x² - 2x + x - 4
8x² - x - 4
Your option will be the third option
Answer: 40.6
Step-by-step explanation:
When finding perimeter, you have to add all sides. 16 plus 16 equals 32. 4.3 plus 4.3 equals 8.6. 8.6 plus 32 equals 40.6
Answer:
95/12 as an improper fraction.
The area (in square feet) of a trapezoid with height h and bases b1 and b2 is 72 square feet
<h3>Area of a trapezoid</h3>
The formula for calculating the area of the trapezoid is given as:
A = 0.5(b1+b2)h
Given the following
h=12
b1=5
b2=7
Substitute
A = 0.5(5+7)*12
A = 12 * 6
A = 72 square feet
Hence the area (in square feet) of a trapezoid with height h and bases b1 and b2 is 72 square feet
