Answer:
a²+b²=c² so you take 15² =225. then you take 8²=64 then you add 225+64=289. Then you find the √289 That equals 17
C=17
Half the perimeter is the length + the width.
Let the width = x
The length is x + 4. ( 4 feet more than the width)
Now you have x + x + 4 = 20
Combine like terms:
2x + 4 = 20
Subtract 4 from both sides:
2x = 16
Divide both sides by 2:
X = 8
The width is 8 feet
The length is 8 + 4 = 12 feet
Answer:
2
Step-by-step explanation:
The slope of the line is found by
m = (y2-y1)/(x2-x1)
= (-2-2)/(-4--2)
= -4/ (-4+2)
= -4/-2
= 2
(18 * 4) + (1500 * .13) = total rental cost
18 * 4 = 72
1500 * 0.13 = 195
72 + 195 = 267
His total rental cost is $267.
