For this case we must simplify the following expression:
We apply distributive property to the terms within parentheses:
We add similar terms:
Thus, the simplified expression is: 
Answer:
Answer:
182
Step-by-step explanation:
take 520 and multiply by 0.35
Answer: 11
Step-by-step explanation: subtract 13 from 24 and then add the existing number on that I think
Answer:
A cos C = 12/13
Step-by-step explanation:
cos theta = adjacent side/ hypotenuse
cos C = BC/AC
But we don't know BC, but we can find it using the Pythagorean theorem
a^2 +b^2 = c^2
5^2 +BC^2 = 13^2
25 + BC ^2 =169
Subtract 25 from each side
BC^2 = 169-25
BC ^2 = 144
Taking the square root of each side
BC =12
cos C = 12/13
Answer:
The first option
Step-by-step explanation:
I just found a place where the lines were on coordinate with whole numbers and replaces the x and y values of the equations (in this case I used 8,3). If the answer was correct, then that was the right equation
