Answer:
43
Step-by-step explanation:
Given
2(p - q) + 5(p + q) ← substitute p = 7 and q = - 2 into the expression
= 2(7 - (- 2)) + 5(7 + (- 2))
= 2(7 + 2) + 5(7 - 2)
= 2(9) + 5(5)
= 18 + 25
= 43
(f+g)(x) = 8x+2
(f-g)(x) = 4x-6
Step-by-step explanation:
Given

we have to find
<u>a. (f+g)(x)</u>

<u>b. (f-g)(x)</u>

Hence,
(f+g)(x) = 8x+2
(f-g)(x) = 4x-6
