Question

Clear parentheses and combine like terms:​

Answer 1

`-40s + 90t + 30`

Explanation:

Given,
`-10(4s - 9t - 3)`

To clear parenthesis using the distributive property of multiplication, we have,

`-10(4s) -10(-9t) -10(-3)`

Negative sign multiplied by negative sign = positive sign

`= -40s + 90t + 30`

Thus:

`-10(4s - 9t - 3) = -40s + 90t + 30`
