The perimeter of a stop sign has a perimeter of 16x2 - 80x. What is the length of one side?

uranmaximum [27]

Since a stop sign is an octagon it has eight sides. So the perimeter will be:

p=8x, p=perimeter and x=side length. We are told that the perimeter is equal to:

16x^2-80x so we can say:

16x^2-80x=8x subtract 8x from both sides

16x^2-88x=0 factor out 8x

8x(2x-11), since we know x>0

x=11/2

x=5.5 units

Help please!!!!!!!!!!!!!

KatRina [158]

Hello!

For this you can plug in the x values in the choices and see if you get the y value

y = $-4^{3} - (-4)$

-4^3 is -64

when you subtract a negative you are just adding

-64 + 4 = 60

Then you do the second one

$y = -3^{3} - (-3)$

-3^3 is -27

-27 + 3 is -24

Then the third one

$y = -2^{3} - (-2)$

-2^3 is -8

-8 + 2 is -6

Then the last one

$y = -1^{3} - (-1)$

-1^3 is -1

-1 + 1 = 0

Since we did not get -2 the answer is D

Hope this Helps!

How do you write equation for rise ove run

SashulF [63]

Y = mx + b

M= your slope or rise over run

B = your y-intercept

For example if the rise was 5 and the run is 6, the equation would say
y = 5/6 + b
The / being your fraction bar

The y-intercept is where your line crosses the y-axis
So say that the line crosses the y-axis at 10
y = 5/6 + 10

That about sums it all up!
