I think the answer is 13.5 square units.
Answer:
x³ + 5x² + 5x - 2
Step-by-step explanation:
Combine like terms.
x³ + 3x² − x + 2x² + 6x − 2 =
= x³ + 5x² + 5x - 2
Answer:
First, find the area of the surface of the shed. Two walls will have an area of 14 x 8 and two walls will have an area of 18 x 10. We get the equation 2(14x8) + 2(10x8) = 224 + 160 = 384 square feet
Next, divide the square footage of the shed's surface by 250 to find how many gallons of paint are needed. 384/250 = 1.54 gallons of paint (rounded to the nearest hundredth)
For the triangle questions, remember that the area of a triangle is 
It would be a RECTANGLE proportional to the base of the pyramid.
