Answer:

(x + 2)(x² - 2x +4)

Step-by-step explanation:

The sum of cubes factors as ...

(a³ +b³) = (a +b)(a² -ab +b²)

Here, you have a=x, b=2, so the factorization is ...

x³ +8 = (x +2)(x² -2x +4) . . . . . . matches the first selection

Ghella [55]

Answer: 19 years to reach 98 inches

Step-by-step explanation:

Its already 3 inches tall, if it grows 5 inches every year or expected to it would take : 3 + 5 = 8

8 + 5 = 13

13 + 5 = 18

18 + 5 = 23

23 + 5 = 28

28 + 5 = 33

33 + 5 = 38

38 + 5 = 43

43 + 5 = 48

48 + 5 = 53

And it goes on until 98 inches. Leaving your answer : 19 years.

Lesson Posttest

kykrilka [37]

Answer:

The probability of getting a 3 on each die is $\frac{1}{3}$

Step-by-step explanation:

Step one

The sample space for tossing two dice is 12

i.e the first die={1,2,3,4,5,6}= 6

and the second die = {1,2,3,4,5,6}= 6

making a total of 12 sample spaces.

Step two

Hence the probability of getting a 3 on each side is

pr(3 on each side) = $\frac{1}{6} +\frac{1}{6}$

pr(3 on each side) = $\frac{1+1}{6}$ = $\frac{2}{6} = \frac{1}{3}$

pr(3 on each side) = $\frac{1}{3}$
