Answer:

72x

Step-by-step explanation:

8x = 2 * 2 * 2 * x   = 2³ * x

18x = 2 * 3 * 3 * x = 2 * 3² * x

LCD = 2³ * 3² * x = 8 * 9 * x = 72x

<h3>Answer:  95 base 10</h3>

===========================================================

Explanation:

Check out the table below. Each 1 and 0 corresponds to a power of 2. A 1 indicates that we'll add on that power of 2 while a 0 means we ignore it. We will add up the items in the second row that correspond to a "1" in the first row.

We get:

2^6+2^4+2^3+2^2+2^1+2^0 = 64+16+8+4+2+1 = 95

Effectively, we add nearly everything in the second row except for the 2^5 term.

Therefore, the number 1011111 base 2​ is equivalent to 95 base 10.

Answer:

2c

Step-by-step explanation:

8c^3           2c^2

------------ ÷ -------------

6 (c+d)       3c+3d

Factor the 3 out of the denominator in the last  term

8c^3           2c^2

------------ ÷ -------------

6 (c+d)       3(c+d)

Since this is division, we can use copy dot flip

8c^3          3(c+d)

------------ * -------------

6 (c+d)       2c^2

We can cancel the (c+d) in the denominator on the left and the numerator on the right

8c^3          3

------------ * -------------

6                2c^2

We can cancel c^2 from the numerator on the left (leaving a c) and the denominator on the right

8c             3

------------ * -------------

6                2

24c

-----

12

24/12 = 2  so we are left with

2c
