Answer:
The length of the rectangle 'l' = 20
The width of the rectangle 'w' = 14
Step-by-step explanation:
<u>Explanation</u>:-
Let 'x' be the width
Given data the length of a rectangular patio is 8 feet less than twice its width
2x-8 = length
The area of rectangle = length X width
Given area of rectangle = 280 square feet
x(2x-8) = 280
2(x)(x-4) =280
x(x-4) =140
x^2 -4x -140=0
x^2-14x+10x-140=0
x(x-14)+10(x-14)=0
(x+10)(x-14) =0
x = -10 and x = 14
we can choose only x =14
The width of the rectangle 14
The length of the rectangle 2x-8 = 2(14)-8 = 28 -8 =20
The length of the rectangle 'l' = 20
The width of the rectangle 'w' = 14
Answer:
The constant cost of dog food is $1.59 per pound.
Step-by-step explanation:
Divide each pound by the cost and you get $1.59
Answer:
the answer is A because the cost of the more expensive one is 15+20=35 multiplied by 3 which will give me =$105
And the cheaper one is 15+20=35 multiplied by 1.50 = which is 52.5
so the amount more of the choice for the more expensive one is 105-52.5=52.5.
the answer is 52.50.
