After you have plotted the graph of the polynomial, the x-intercepts of the given polynomial will be:
(-3,0),(-1,0) and (4,0)
therefore the interval will be:
(-∞,-3)-below, (-3,-1)-above,(-1,4)-below,(4,∞)-above
The answer is ]
2.5 plus 13.5 times 10
Hope that helps
Answer:
Step-by-step explanation:
The distributive property: <em>a(b + c) = ab + ac</em>.
Alright so since the area of one side of the door is 2,880 inches squared and he wants to paint both sides, you must multiply that by 2.
2880 * 2 = 5760
Since he wants to put 2 coats of paint, this essentially means he wants to paint over everything twice so you must multiply by 2 once more.
5760 * 2 = 11520
This being the total surface area we are going to need to paint. So now we must discover the least amount of money Luke must pay. Knowing we need to cover 11,520 inches worth of door:
4400 * 2 = 8800
8800 + 2200 = 11000
This means we either need to pay another $7 or just buy three gallons.
Best option: Purchase 3 gallons of paint costing 30$
30$
