A = L * W
A = 44
L = 2W - 3
44 = W(2W - 3)
44 = 2W^2 - 3W
-2W^2 + 3W + 44 = 0
(-2W + 11)(W + 4) = 0
W + 4 = 0
W = -4......not this one because it is negative
-2W + 11 = 0
-2W = -11
W = -11/-2
W = 5.5 <=== width is 5.5 yds
L = 2W - 3
L = 2(5.5) - 3
L = 11 - 3
L = 8 <=== length is 8 yds
1. 4
2. 14
should be correct
Answer:
Let b be the number of branches that the shrub will have after m months, since the shrub has an initial amount of 12 branches and the shrub grows 4 new branches every month, then we can set the following equation:
Evaluating the above equation at m=7 we get:
Simplifying the above result we get that the shrub will have
branches after 7 months.
Answer:
22.5^3
Step-by-step explanation:
V=length*width*height=2*2.5*4.5=22.5 m^3
