Step-by-step explanation:

A = base *h /2

A = (4*15/2 )/2 = 15 in²

A = (1 and 3/7 *14/5 )/2 = (10/7 * 14/5 )/2 = 2 in²

A= (5 and 2/7 * 7/2) /2 = (37/7 * 7/2)/2 = 9.25 in²

Given the following functions, find each: f(x)=x2+5x−14 g(x)=x−2 (f+g)(x)= (f−g)(x)=

lions [1.4K]

Answer:

(f+g)(x) = x²+5x-14 + (x-2)

= x²+5x-14+x-2 = x²+6x-16

(f-g)(x) = x²+5x-14 - (x-2)

= x²+5x-14 - x+2

= x²+5x-14-x+2 = x²+4x-12
