What values of cand d would make the following expression represent a real number?
i(2 + 31)(c + di)
- C = 2. d = 3
C= -2, d = 3
c = 3, d= -2
C = -3 d = -2

answer: 7

step-by-step explanation:

236 cm 16 time 12 = 192

6 times 7 = 42

192+42

answer: -10

step-by-step explanation:

s(t) = 1 - 10t

s(x) = 1 - 10x

s(x + h) = 1 - 10(x + h)

            = 1 - 10x - 10h

s(x + h) - s(x) = 1 - 10x - 10h - (1 - 10x)

                      = 1 - 10x - 10h - 1 + 10x

                      = -10h

= -10
