X^2 - 4x + 4 = 0
(x - 2)^2 = 0 - Factor left side
x - 2 = 0 - Square root each side
x = 2 - add 2 to each side
Answer:
She needs to sell the rest of her <u>29.41 </u>rolls of wrapping paper. If she sells all of her rolls of wrapping paper, she'll be able to get a total of <u>$131.48.</u>
Step-by-step explanation:
To get the answer to "<u>How many more rolls of wrapping paper does Daisy need to sell?"</u> you would have to add up how many she already sold which is
2.24 + 5.75 + 0.6 = 8.59
and then subtract 8.59 from the total of rolls she's supposed to sell.
38 - 8.59 = 29.41
To get <u>$131.48</u>
You multiply how much each roll costs to the total of rolls she's supposed to sell:
38 * 3.46 = <u>131.48</u>
Hope this helped :)
Answer:
The area of the counter that Carlos will wall tile is 
Step-by-step explanation:
to solve this, we will calculate the area of the counter and the area of the rectangular hole that Carlos would have to leave out for the sink, and then subtract them to get the area that will be tiled.
Total area of the rectangular counter = length X breadth = 
area of the rectangular cut out for the sink = length X breadth =
Surface area that Carlos is meant to tile = 
Hence,the area of the counter that Carlos will wall tile is 
the horizontal tangent line mean y'=0
8 - 2x = 0
x = 4
The answer is given above
