Answer:
$55,200
Step-by-step explanation:
Area of yard = length * breadth
So,
Area = 50*46 = 2300 sq. feet
Again,
Cost per sq. feet = $24
So, For 2300 sq. feet,
Total cost = $24*2300 = $55,200
Hope it helped!
Answer: B. -4 5/12
Step-by-step explanation:
I'm not sure what you mean by "the 3 consecutive numbers of 72".
Do you mean 3 consecutive numbers that ADD UP TO 72 ?
If that's what you want, then you can use this equation:
The middle number . . . . . x
The smallest number . . . . (x-1)
The biggest number . . . . . (x+1)
The equation: (x-1) + (x) + (x+1) = 72 .
Boil that equation down, and you discover that x=24 .
So the 3 numbers are 23, 24, and 25 .

Answer:
The perimeter is the distance all the way around the outside of a 2D shape. To calculate the perimeter, sum the lengths of all the sides.
Therefore, perimeter of the triangle = (2x - 8) + (2x + 5) + (30 - 3x)
Collect like terms: 2x + 2x - 3x - 8 + 5 + 30
Combine like terms: x + 27
Therefore, perimeter of triangle = x + 27
We are told that the perimeter is 25:
x + 27 = 25
Subtract 27 from both sides: x = -2
If x = -2, then the side with equation 2x - 8 = (2 x -2) - 8 = -12
A length cannot be negative, therefore the perimeter cannot equal 25.
