36+27i because /-9/ equals 9 so you distribute 9 in the parentheses then you add like terms
Since we know that the area is 100 and we are dealing with a square, that means that all sides are equal. We know that the sides are all 10 because 10*10= 100.
To find the perimeter, we add up all the sides: 10+10+10+10 = 40m
Answer:
20
65
95
Step-by-step explanation:
Remark
You have to use a constant to get the ratio so that it will produce angles that will add up to 180. Let that constant = x
Equation
4x + 13x + 19x = 180
Solution
Add the like terms on the left.
36x = 180
Divide both sides by 36
36x/36 = 180 /36
Combine
x = 5
Answer
4x = 20
13x = 65
<u>19x = 95</u>
Total = 180
