Answer:
$480
Step-by-step explanation:
10x12x4
Answer:
54 feet
Step-by-step explanation:
The perimeter of the room is the sum of wall lengths:
2·(15 feet) + 2·(12 feet) = 30 feet + 24 feet = 54 feet
The border should be cut to 54 feet.

<em>Comment on the question</em>
This seems to be a math problem designed to get you to figure the perimeter of the room. If you were actually installing wallpaper, you might want to cut the border in four (4) pieces, each slightly longer than the corresponding wall. That way any lack of squareness in the corners could be managed more easily, and the possibility of a gap at the seam could be eliminated.
Y²/58² + x²/b² = 1
<span>(0,58), (-21,29), and (21,29) are points on the ellipse. </span>
<span>29²/58² + 21²/b² = 1 </span>
<span>¼ + 21²/b² = 1 </span>
<span>21²/b² = ¾ </span>
<span>4·21²/3 = b² </span>
<span>b² = 588 </span>
<span>y²/3364 + x²/588 = 1</span>

oki! Mizuki is here to help!
The answer is 61 cars!
Step-by-step explanation:
<em>First, let's find how much money she needs to earn!</em>
105 + 500 = 605
<em>Then, we will divide the amount she needs to earn by the amount per each car!</em>
605 ÷ 10 = 60.5
<em>We get 60.5 As an answer but... since we must wash a whole car, we will round it up and get 61 cars as the answer!</em>
Answer:
8 - 42x - 56y - 12xy
Step-by-step explanation:
Length = 4 - 7(3x + 4y)
= 4 - 21x - 28y
Width = 3x(-2y)
= -6xy
Perimeter of the rectangle = 2(length + width)
= 2{(4 - 21x - 28y) + ( -6xy)}
= 2(4 - 21x - 28y - 6xy)
= 8 - 42x - 56y - 12xy
Perimeter of the rectangle = 8 - 42x - 56y - 12xy
