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
Answer:
You selected the correct answer: {x | x <<em> </em>-4 or x > 2}
Step-by-step explanation:
5(x - 2)(x + 4) > 0
Use FOIL method to expand (x - 2)(x + 4):
> 0
Distribute 5 into
> 0
Divide all terms by 5 from both sides of the inequality:
Factor the trinomial:
(x + 4) ( x - 2) > 0
x < -4 or x > -2
Therefore, the solution set to the inequality is {x | x < -4 or x > 2}
