Answer:
(x - 4)³
Step-by-step explanation:
"The cube of x" would be x³. The difference of a number and 4 would be x - 4.
Therefore, "the cube of the difference of a number and 4" would be
(x - 4)³
The perimeter of a rectangular field is 364 yards. If the width of the field is 84 yards, what is its length?
(364 : 2) - 84 =
182 - 84 =
98
In the comment of the other answer, you said that the rectangle is 24 x 18 ft.
First, we have to find out how many square feet that is, and then we can convert it to square yards.
The area of a rectangle is the length multiplied by the width.
A = l x w
A = 24 x 18
A = 432 square feet
To find out how many square yards that is, we divide it by 3, because 1 yard is 3 feet.
432 ÷ 3 = 144
The area of a 24x18ft rectangle is 144 square yards.
Company A : 13 + 30m.....where m = # of mattresses
company B : 15 + 28m.....where m = # of mattresses
==============
company A : cleaning 4 mattresses : 13 + 30(4) = 13 + 120 = 133
company B: cleaning 4 mattresses : 15 + 28(4) = 15 + 112 = 127
so company B would charge less
==============
company A : cleaning 7 mattresses : 13 + 30(7) = 223
company B: cleaning 7 mattresses: 15 + 28(7) = 211
so by using company B, u would save : 223 - 211 = $ 12
