Answer:
So the equation in standard form will be
Step-by-step explanation:
We have given equation 
We have to write this expression in standard form
For writing in standard form first we have to do operation on the expression
We know that there is property of exponent that when two functions are multiplied with each other then there exponent are added
So 
So the equation in standard form will be 
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
Answer:
k = 3.70
Step-by-step explanation:
Eliminate parentheses, then subtract the constant term on the left
8.5 +4 -10k = -24.5
-10k = -37 . . . . . . . . . . 12.5 subtracted from both sides
k = 3.70 . . . . . . . . . . . both sides divided by -10 (no rounding required)
