If f(x) = 2x - 5 and g(x) = x^2 - 4x-8 , find (f+g) (x) ( do not just input answer without reasoning ) my options : a. (f + g) ( x) = x^2 + 2x - 3 b . (f + g) ( x) = x^2 - 2x - 13 c. (f + g) ( x) = 3x^2 - 4x - 13 d. (f + g) ( x) = x^2 - 2x - 3

We know that According to Algebra of Real Functions :  

If f and g are two real functions which are defined under the same domain then (f + g)(x) = f(x) + g(x)

Given : f(x) = 2x - 5 and g(x) = x² - 4x - 8

⇒ (f + g)(x) = f(x) + g(x) = (2x - 5) + x² - 4x - 8

⇒ (f + g)(x) = f(x) + g(x) = x² - 2x - 13

Option B is the Answer

step-by-step explanation:

hans did not square the 40-unit side; he merely multiplied it by 2.   incorrect.

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180
