1. 5( 2X - 4.1 )

5*2x - 5*4.1

10x - 20.5

2. -4 ( -3X - 5.2 )

12x + 20.8

3. 3 ( 5X + 3X )

15x + 9x

4. 7 (2 + 4X)

14 + 28x

Calm down. Press CAPS LOCK. Breathe.

There's basically no work to show without being trivial.

1) 10x - 20.5

2) 12x + 20.8

3) 15x + 9x = 24x

4) 14 + 28x

To distribute, multiply the number outside the parentheses by each term within the parentheses. Don't forget to include negatives and positives. If you seriously want work for it to see how it's done, here's work for the second one:

-4(-3x - 5.2)

[-4(-3x)] + [-4(-5.2)]

12x + 20.8

so what you need to do is multiply the ouside number by everything inside the brackets to get rid of the brackets

1. 10x-20.5 or in other words 5*2x+ 5*(-4.1)

2. 12x+21 remember two negatives = a positive

3.15x + 9x if numbers have the same variable you can add them

24x

4. 14 +28 x

I hope this helps you understand !

5(2X - 4.1)

(5(2X) + 5(-4.1))

(10X - 5*4.1)

(10X - 20.5)

10X - 20.5

-4(-3X - 5.2)

(12X + 20.8)

12X + 20.8

3(5X + 3X)

Since 5X and 3X are like terms, add 3X to 5X to get 8X.

3(8X) = 24X

7(2 + 4X)

Reorder from left to right, starting with the highest order term.

7(4X+2)

Multiply 7 by each term inside the parenthesis.

28X+14
