Let x = width
<span>length is 8 cm more than three times it’s width so length = 3x + 8
</span>
Perimeter of a rectangle = 2(L + W)
so
128 = 2(x + 3x + 8) solve for x (width)
128 = 2(4x + 8)
64 = 4x + 8
4x = 56
x = 14
width = 14 cm
length = 3(14) + 8 = 50 cm
Answer:
width = 14 cm
length = 50 cm
The answer is 0.0017. Do you not have a calculator?
The answer is 0 unless I did the math wrong
If so someone correct me. Other than that, hope this helped!
Answer:
Graph of Option D represents
Step-by-step explanation:
we are given our function as
squaring on both sides we get
It represent a parabola opening towards the positive side of x axis. Hence it gives us some preliminary idea about the graph of the function we are given .
However our original function is 
Domain of
is all positive values of x
And square root of positive values will always result in positive values. Hence y can not be negative as the range is All positive values of y
Hence we erase the graph of
below x axis to obtain the graph of

-8x - 60 = -164
Add 60 to both sides, because whatever you do on one side, you have to do it to the other side
-8x = -104
Divide -8 to both sides
x = 13
