Answer:
compute its exterior angle as 360/18, which is 20 degrees
Step-by-step explanation:
Well first you take 78 and turn it to 7.8
then multiply by 10000
therefore 7.8*10000= ?
The formula is y = mx+b where m is the slope and b is the y intercept.
y = 0x + b
7 = (-6)0 + b
7 = 0 + b
b = 7
y = +7
Answer:
Cost of one roll of plain wrapping: 
Cost of one roll of holiday wrapping paper: 
Step-by-step explanation:
Let be "p" the cost in dollars of one roll of plain wrapping paper and "h" the cost in dollars of one roll of holiday wrapping paper.
Based on the information given, we can set up this system of equations:

In order to solve it, we can use the Substitution method. The steps are:
1. Solve for "p" from the first equation:

2. Substitute the above into the second equation and solve for "h":
3. Substitute the value of "h" into
:

So the culture banner size has length x, width x (since it is square)
The sports banner has length x+12, width x.
The area of the sports banner is length x width = x(x+12) = x²+12x.
Now, lets look at the tiles.
- The monomial, x, a factor of the expression is the width of the sports banner.
- The binomial (x+12) is the length of the spots banner (this is given!)
- The second degree term of the expression x²+12 is x², the area of the culture banner
- The first degree term of the expression x²+12x is 12x, it represents the increase in area, since the area went from x² to x²+12x
