Simplify 8(x + 6) - 10. 8x + 38 8x - 4 8x + 28

Serga [27]

Answer:

$8x+38$

Step-by-step explanation:

We want to simplify $8(x+6)-10$

We expand using the distributive property to get:

$8(x+6)-10=8x+8*6-10$

This implies that:

$8(x+6)-10=8x+48-10$

We perform the subtraction now to get:

$8(x+6)-10=8x+38$

colleen's family plans to paint the windows of their house. her father will paint twice as many windows as her mother, and Colle

Morgarella [4.7K]

Answer: 24

Step-by-step explanation:

Colleen painted 7 windows, some of which were her mother's.

Her dad painted 7+1 (8) windows, and that is twice as much as what her mother was supposed to do. Her mother was supposed to do 4 windows. That means Colleen's share was 3 windows.

If all the kids had to do an equal amount of windows, than each kid had to do 3 windows.

8+7+3+3+3=24
