Question

if p(x) = x+ 7/ x-1 and q (x) = x^2 + x - 2, what is the product of p(3) and q(2)? a. 50 b. 45 c. 40 d. 20 e. 6

Answer 1

d. 20

Step-by-step explanation:

p(x)= x+7 / x-1

p(3)= 3+7 / 3-1 = 10/2 = 5 (where x=3)

again,

q(x)= x^2+x-2

q(2)= 2^2+2-2 = 4+2-2 = 4 (where x=2)

so,

p(3) x q(2) = 5x4 = 20

Answer 2

d. 20

Step-by-step explanation:

P(3) = 3 + 7 / ( 3-1) = 10/2 =5

q(2) = 2^2 +2-2 = 4 + 2 -2 =4

P(3) * q(2) = 5 * 4 = 20
