D. Subtract 2 from the number of sides and multiply the difference by 180
Answer:
Step-by-step explanation:
<u>Fractions</u>
We are given the expression:
We'll find an equivalent expression that results when simplifying the given fraction.
The numerator is a mixed fraction, which we'll convert into an improper fraction as follows:
Now it follows:
Instead of dividing fraction, we multiply by the reciprocal of the denominator:
Simplifying:
Answer:
Parralel lines have the exact same slope.
in the equation y=mx+b m is the slope
Both of these equations are in slope intercept form (y=mx+b) meaning that the coefficient in both equations is the slope.
Parralel lines have the same slope and perpendicular lines have the inverse opposite slope. For example if a line had a slope of 2 or 2/1 then the perpendicular line to it would have a slope of -1/2.
With that knowledge we can easily see that the lines are perpendicular since their slopes (represented by the coefficient) are the inverse opposite.
Perpendicular is your answer
Step-by-step explanation:
X^2+3x+1+4x-1+2x^2
Combine like terms:
x^2+2x^2=3x^2
3x+4x=7x
1+(-1)=0
Solution:
3x^2+7x
All you can do here is simplify it
Answer:
Mr.Riley collected $376.
Step-by-step explanation:
First it says there are 1692 cookies and 36 boxes. When you put 1692 cookies into 36 boxes its the same thing as 1692 divided by 36 which is 47.
Then it says each box cost $8. So there are 47 cookies in 36 boxes and each box cost $8 which is the same as multiplying 47 by 8 which is $376.
