Answer:
Step-by-step explanation:
Let's call the width: w
the lenght is then 3w+4 ("4 more than 3 times the width")
and the parameter would be 2(w+3w+4), that is 2*(4w+4), that is 8w+8.
this is also equal to 18.4:
8w+8=18.4
8w=10.4
w=1.3
this is the width, and the lenght is:
4+3*1,3=4+3.9=7.9
and the area is their product:
1.3*7.9=10.27
Because the answers are all in standard form, we can simply look for the intercepts of the graph.
x-int = (-6, 0)
y-int = (0, -2)
You must multiply these numbers by a coefficient to equal 12:


Solve both equations by dividing by their values:


Look for the answer with these coefficients. The answer is
-6x - 2y = 12.
Answer:
19200 ft
Step-by-step explanation:
first you convert it based on 1 in = 20 ft
8*20=160
6*20=120
now you multiply to find area
remember area is a = lw
160*120=19200
add units
19200 ft
