1/4 would be the answer. Let me explain why first. You have in total 4 numbers with different out comes when added together. So your equation will start out as 4² = 16 out of the 16 different factors you have 4 sets that equal 180°. Your new fraction would be 4/16 which can be divided by 4 to equal 1/4. Hopes that helps!
Answer:
The value of the given expression is -878.08.
Step-by-step explanation:
Here, the given question is INCOMPLETE.
The complete question is:
Evaluate the expression for a = 4, b = -5, and c = -7. 
Here, substitute the vale of a = 4, b = -5 and c = -7, we get:

Hence, the value of the given expression is -878.08.
The answer to your problem is C
Convert 2/5, 1/4 and 7/10 to fractions with like denominators.


Since 8/20,5/20 and 14/20 have the same denominator, add their numerators to add them up.
