Answers with step-by-step explanation:

1. (7x + x) + 7x

= 7x + 7x + x

= 14x + x

= 15x

2. 5 * (4 * x)

= 5*4x

= 20x

3. 15y + (x + 9y)

= 15y + 9y + x

= 24y + x

4. (6x + 21) + 14

= 6x + 21 + 14

= 6x + 35

5. 3x + 2 + 11x

= 11x+ 3x + 2

= 14x + 2

6. (x + 13y) + 8y

= 13y + 8y + x

= 21y + x

7. (12y + 2x) + 4y

= 12y + 4y + 2x

= 16y + 2x

8. 8 (x4)

= 32x

9. 3 (5x)

= 15x

10. 3x + (7x + 10)

= 3x + 7x + 10

= 21x + 10

11. 5x + (2 + x)

= 6x + 2

12. 4 * x * 10

= 4 * 10 *x

= 40x

13. (x * 12) * 3

= 36x

14. 14x + 9y + 6x

= 20x + 9y

15. 5x + (24 + 14x)

= 19x + 24

Find the probability of rolling a 6 on a number cube and flipping heads on a coin
serious [3.7K]

Assuming that the number cube is 6 sided

6 is one number in a 6 sided cube, so the probability is: 1/6

heads is one side of the coin, with two in all: 1/2

Multiply the two fractions together

1/6 x 1/2 = 1/12

1/12 is your probability

hope this helps

Evaluate the function at each specified value of the independent variable and simplify. (if an answer is undefined, enter undefi
tekilochka [14]

For this case we have the following function:

h (t) = t ^ 2 - 8t

What we should do is evaluate the function for the different values of the independent variable.

We have then:

For x = 8:

h (8) = (8) ^ 2 - 8 (8)

h (8) = 64 - 64

h (8) = 0

For x = 1.8:

h (1.8) = (1.8) ^ 2 - 8 (1.8)

h (1.8) = 3.24 - 14.4

h (1.8) = -11.16

For x = x + 8:

h (x + 8) = (x + 8) ^ 2 - 8 (x + 8)

h (x + 8) = x ^ 2 + 16x + 64-8x-64

h (x + 8) = x ^ 2 + 18x

Answer:

The results of evaluating the function are:

h (8) = 0

h (1.8) = -11.16

h (x + 8) = x ^ 2 + 18x
