Answer:

3x+12

Step-by-step explanation:

3(x+4)

We distribute the 3 to both terms inside the parenthesis

3*x + 3*4

3x+12

[] Answer []

$\boxed{(3 \ * \ X) \ + \ (3 \ * \ 4)}$

$\boxed{3x \ + \ 12}$

[] Explanation []

Distributive Property:

$a(b \ + \ c) \ = \ (a \ * \ b) \ + \ (a \ * \ c)$

3(X + 4)

= (3 * X) + (3 * 4)

3 * X = 3x

3 * 4 = 12

= 3x + 12

When using the Distributive Property, you distribute the numbers into another equation. Doing this simplifies the expression making it easer to solve.

$\boxed{[] \ Eclipsed \ []}$

Question 9 of 15 (1 point)

mote1985 [20]

The number is -9

Step-by-step explanation:

Let x be the number then according to given statement

$4x+10 = x-17$

Subtracting 10 from both sides

$4x+10-10 = x-17-10\\4x = x-27$

Subtracting x from both sides

$4x-x = x-x-27\\3x = -27$

Dividing both sides by 3

$\frac{3x}{3} = \frac{-27}{3}\\ x = -9$

<u>Verification:</u>

$4(-9)+10 = -9-17\\-36+10=-26\\-26=-26$

The number is -9

The numbers 1-4 are each written on an index card. The 4 cards are put into a bag and 2 of them are drawn at random. What is the

devlian [24]

Answer:

Step-by-step explanation:

Write a list of all possible outcomes

1-2

1-3

1-4

2-1

2-3

2-4

3-1

3-2

3-4

4-1

4-2

4-3

There are 12 possible outcomes. How many of them have totals of 6 or 7

I count 4

So the probability is 4/12 = 1/3, just as you said.

Is there an easier way?

You might be able to get the 12 easier.

You have 4 choices for the first number and 3 for the second.

P(12) = 4*3 = 12

Getting 6 or 7 might be somewhat trickier.

4 and 3 make seven. That gives two ways 4-3 and 3-4

4 and 2 make six. That gives 2 more ways 4-2 and 2-4

That's all that's possible.

answer: 4 ways make success. The total number of ways is 12.
