Let w be the width of the second garden. Then, its' length is 2w+4. So:
w(2w+4)=70
2w²+4w-70=0
w²+2w-35=0
(w+7)(w-5)=0
w=5
2w=10
2w+4=14
The first garden is 5m x 10m, the second is 5m x 14m

108
Step-by-step explanation:
2(1.5)(6^2)=3(36)=108
Answer:
The answer in C
Step-by-step explanation:
we can see from the graph on C that it goes up #20 every hour
Ok. So first, we calculate the slope!
m=(y2-y1)÷(x2-x1)= (5-2)÷(3-1)=3/2.
Now that we have the slope, we can start to write an equation for the line by plugging in the given points. b is the y-intercept.
y=mx+b.
2=(3/2)1+b
b=2-(3/2)=2-1.5=.5 or 1/2
so the y-int is (0,.5 or 1/2) .
Next, we have to find the x-int.
to do that, we just plug in 0 for the y.
0=1.5x+.5
x=-.5/1.5= (1/3)
so the x-intercept is
(1/3 or .33,0).
