Answer:
Yes, (-6,-38) is a coordinate pair off the equation
Step-by-step explanation:
Plug y=7x+4 into your graphic caculator
press 2ND, GRAPH and scroll up to see the point.
length = 3234 m and width = 1614 m
let the width = w then length = 2w + 6
Perimeter = 2 ( length + width )
= 2 (2w + 6 + w ) = 2 ( 3w + 6 ) = 6w + 12
given perimeter = 9696 the equating gives
6w + 12 = 9696
subtract 12 from both sides
6w = 9696 - 12 = 9684
divide both sides by 6
w = 
= 1614
width = 1614 m and length = (2 × 1614 ) + 6 = 3234 m
The first problem Levi solves is incorrect, because 5/4 is not equal to 20.
The second problem Levi solves is correct, because 1.5 x 10 is 15, which subtracting 8 is equal to 7.
The third problem Levi solves is correct, because 4 x 13 is 52 and plus 6 it is 58.
I hope this helps!
let the length of each shorter side be x
length of longer side= x+14
2(x+14) + 2x = 48
2x + 28 + 2x = 48
4x + 28 = 48
4x = 48-28
4x = 20
x = 5
shorter side = 5cm
