A(h)=4h+70, A(h)=dollars to rent for h hours, h=hours rented.
B(h)=5h+60, same variable explanations...
....
To compare the two values at 6 hours you have:
A(6)=4(6)+70=24+70=$94
B(6)=5(6)+60=30+60=$90
So at 6 hours Company B would charge $4 less than Company A
...
Savings at 7 hours of rental by using B instead of A is:
S(h)=A(h)-B(h)
S(h)=4h+70-5h-60
S(h)=-h+10
S(7)=-7+10=$3
So at 7 hours, Company B saves you $3.
Similar triangles are triangles that has all sides and angles to be equal. The value of x if , ΔGEF and ΔHEF are congruent is 28
<h3>Similar triangles</h3>
Similar triangles are triangles that has all sides and angles to be equal. From the given diagram;
<GFE = <EFH
Given
<GFE = 60 degrees
<EFH = 2(x+2)
Substitute
2(x+2) = 60
2x + 4 = 60
2x = 60 - 4
2x = 56
x = 28
Hence the value of x if , ΔGEF and ΔHEF are congruent is 28

Answer:
12
Step-by-step explanation:
912 - 612 = 300
300 ÷ 25 = 12
P = 2(L + W)
P = 86
L = W + 11
86 = 2(W + 11 + W)
86 = 2(2W + 11)
86 = 4W + 22
86 - 22 = 4W
64 = 4W
64/4 = W
16 = W
L = W + 11
L = 16 + 11
L = 27 <====
