Answer:
40
Step-by-step explanation:
remember PEMDAS
our equation looks like tihs: 
1. parentheses: in the denominator we have a parentese inside of another parenthese, so start with the inside first: (3-5) = -2.
so now our equation looks liek this 
now we have a mini PEMDAS situation within the parentheses: multiplication comes before addition/subtraction, so multiply -2*2 = -4, so now your equation looks like this: 
6-4 =2: so now we're done with parentheses part of PEMDAS, the only thing left is dividing 80/2 which equals 40.
Answer:
45 °
Step-by-step explanation:
m< ABC = m< DBC + m< ABD
= 115 _ 70
= 45 °
The monomial x would be the length of the sports banner.
-We know this because we typically use a basic variable for the thing that does not change. In this case, the length of the sports banner remains the same.
The second degree term in the expression would be the increase in area of the culture banner to make the sports banner.
-We can tell this because when we increase the width of the banner by 12, the resulting polynomial is 12x larger than x^2 (which was the original area of the culture banner.
The binomial expression x + 12 would be the width of the sports banner.
-Since we are increasing the width of the culture banner from x, x + 12 would represent the new width of the sports banner.
The first degree term in the expression would be the area of the culture banner.
-Because side of the culture banner is the same before the increase, multiplying x by itself will give you an area of x^2. This is the first degree term.
C would be the answer because to find the area of a circle A=pi times radius squared and you put that in a calculator and get 50.24
