Answer:
20, 22, 28, 50
Step-by-step explanation:
The length and width could be:
1, 1, 24, 24
2, 2, 12, 12
3, 3, 8, 8
4, 4, 6, 6
1+1+24+24= 50
2+2+12+12= 28
3+3+8+8= 22
4+4+6+6= 20
Answer:
The break- even point is attained when n=75
Step-by-step explanation:
The break-even point is defined as the point where revenue is equal to cost.
We take the equation for revenue r=15n, and set it equal to the equation c=9n+450
15n=9n+450
Subtract 9n from both sides:
6n=450
Divide both sides by 6.
6n/6=450/6
n=75
The break- even point is attained when n=75....
ANSWER:
square root of ( 100x^2 + 60x + 9 )
An expression to represent the length of each side of the rug is:
square root of ( 100x^2 + 60x + 9 )
STEP-BY-STEP EXPLANATION:
Let's establish that the area of a square is the length of one of its sides squared.
Area of square = Side^2
THEREFORE:
To find the length of each side of the square, we will make side the subject in the formula as displayed below.
Area of square = Side^2
Side^2 = Area of square
Side = square root of ( area of square )
From this, we will substitute the given expression for the area of the square rug to obtain the expression for the length of each side of the rug.
Side = square root of ( 100x^2 + 60x + 9 )
