Answer 1

4(d)

The given expression is 7h+8g+2h+g.

Solve as follows:

`7h+8g+2h+g=7h+2h+8g+g`

`=(7+2)h+(8+1)g`

`=9h+9g`

Therefore, the given expression is written as 9h+9g.

4(g)

The given expression is 10q-5q+17-9.

Solve as follows:

`10q-5q+17-9=(10-5)q+8`

`=5q+8`

Therefore, the expression is written as 5q+8.

4(b)

The given expression is 3c+5c+2d+d.

Solve as follows:

`3c+5c+2d+d=(3+5)c+(2+1)d`

`=8c+3d`

Therefore, the given expression is written as 8c+3d.
