Answer:
7x^2 + 2x - 4
Step-by-step explanation:
First, combine like terms: Combine 5x^2 and 2x^2, obtaining 7x^2. Include the 2x term (there is no like term for this one) and combine -10 + 6, obtaining -4.
Then the sum of these two polynomials is
Note: Use " ^ " to indicate exponentiation.
7x^2+2x-4
a standard form is ax+by=c
5x^2 add 2x^2=7x^2 then -2x but when you have a -10 +6 you get -4 giving you the answer of 7x^2 +2x -4
If you add 7 to negative 7, it would be y=0.
Answer: y=0
x= 85 is the answer. ( because exterior angle of a triangle is equal to 2 non adjacent interior angle of a triangle..)
