Zeno is walking in a straight line. With each step, he covers half the remaining distance between him and the end of his path, w

shtirl [24]

8 foot path

1st step = 8/2 = 4ft
2nd step = 4/2 = 2ft
3rd step = 2/2 = 1ft
4th step = 1/2 = 1/2ft

So he covered 7 1/2 ft (or 7.5ft)

If c(x) = 4x - 2 and d(x) = x + 5x what is (c×d)(x)?

g100num [7]

Answer:

24x^2 - 12x

Step-by-step explanation:

C=4x -2

D=x + 5x

(4x - 2) * (x +5x)

4x^2 + 20x^2 - 2x - 10x

=24x^2 - 12x
