A rectangular room has 5a+2bm length and 4a-bm breadth find the area of the room
If a=3m and b=2m, find the actual area of that room.​

Part A)

F(s) = 3s + 35 is the number of flowers

S(w) = 15w is the number of seeds planted

Since s = 15w, replace s in the first equation with 15w and simplify:

F(s) = 3(15w) + 35

F(s) = 45w + 35

B)

The composited equation calculates the number of flowers That bloomed.

C) replace w with 36 and solve.

45(w) + 35 = 45(36)+35 = 1620 + 35 = 1,655 flowers bloomed in 36 weeks.
