Answer:

72cm²

Step-by-step explanation:

perimeter= 2(l+w)

         36  = 2(l+w)

       36/2 = l+w

           18 = l+w

since, l is twice as w

18= 2w + w

18 = 3w    (we can add since all the variables, and exponents are same)

18/3 = w

6= w

NOW,

 w=6  and l is equal to twice as 6

so l=12

area= l×b

        = 12×6 = 72cm²

hope this helps. It was toooo long

I need help with # 14 and 15 ASAP... It is due tomorrow ..can some one please help me with it
Angelina_Jolie [31]

Answer:

See explanation

Step-by-step explanation:

A. Gasoline fill-up fee = $4.50

Cost per hour = $40

Average cost = C

Number of hours the scootcar is rented = h

Cost per h hours = $40h

Total cost = $40h + $4.50

Hence,

C = 40h+4.5

B. To plot the graph of the function, find h- and C- intercepts.

When h = 0, then C = 4.5, and we have point (0,4.5)

When C = 0, then 0 = 40h + 4.5, h = -45/400 = -0.1125, and we have point (-0.1125,0)

Plot these two points and connect them with a straight line.

Graph is attached, but you should take only that part of the graph that corresponds to points with h > 0, because the number of hours cannot be negative
