Answer:
Step-by-step explanation:
<u>Functions have graphs or slopes.</u>
<u>This is not a function.</u>
<u>This is not on a graph or on a slope.</u>
Your answer is not a function.
This is another one for my "impossible math question" file. All of the answer choices are wrong. (None applies.)
According to the problem statement, the length you have marked "x" in the diagram is 15 inches. If the side length of one of the pavers is "s", then the Pythagorean theorem tells us
s² + (2s)² = 15²
5s² = 225
s² = 225/5 = 45 . . . . . . the area of one square is 45 in² (not 225 in²)
Then
s = √45 = 3√5 . . . . . . . the length of one side is not 5√3
so the perimeter is
p = 4s = 4·3√5 in = 12√5 in ≈ 26.83 in . . . . not 75 inches.
The area of the 6-block L-shaped path is
total area = 6s² = 6·45 in² = 270 in² . . . . not 450 in²
And the total perimeter is 14 sides, so is
total perimeter = 14s = 14·3√5 in = 42√5 in . . . . not 60√3 in

In cases like this where the answer key is incorrect, you might try asking your teacher show the class how to work the problem.
Answer:
Its D
Step-by-step explanation:
Rewrite the whole as a fraction using 2 as the denominator :
- 3 is also equal to 3/1
- New problem: 3*2/2
Set up the new problem
New problem: (n+4) - (3*2)/2
this equals: n-2/2
- 13 is equal to 13/1
(n-2) - (13 • 2) n - 28
———————————————— = ——————
2 2
Okay, n-28/2=0
Now, on the left hand side, the 2 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
n-28 = 0

6×3=18 feet.This is the answer
