Answer:
1st answer a 44
Step-by-step explanation:
Answer:
43ft
Step-by-step explanation:
<em>side a = x ft</em>
<em>side b = 10 ft</em>
<em>side c = 18 ft</em>
x = 14.967
rounds to = 15
10 + 18 + 15 = 43
<u>43 ft of fence needed</u>
Answer:
9. 5 Hours
Step-by-step explanation:

x = -2
y = 1
let's multiply second equation by 4 to get a common coefficient of y variable.
16x-8y=-40
add the equations
3×+8y=2
16x-8y=-40
----------------
3x+16x = -38
19x = -38
x = -2
substitute x
3×-2 + 8y = 2
-6 + 8y = 2
8y = 2+6
y = 1
check the answer
-6+8 = 2
-8-2= -20
Rectangle JKLM:
p = 140 ft
w = 30ft
l = (140 - 2(30))/2 = 40ft
A = (30)(40) = 1200 ft²
Rectangle STUV:
l = 8yd = (8)(3) = 24 ft
24ft/40ft = 3/5
so . .
w = 3/5*30 = 18ft
A = 3/5*1200 = 720 ft²
Ratio of area JKLM:STUV = 1200/720 = 5/3
