Answer:
[tex] -40s + 90t + 30 [/tex]
Step-by-step explanation:
Given, [tex] -10(4s - 9t - 3) [/tex]
To clear parenthesis using the distributive property of multiplication, we have,
[tex] -10(4s) -10(-9t) -10(-3) [/tex]
Negative sign multiplied by negative sign = positive sign
[tex] = -40s + 90t + 30 [/tex]
Thus:
[tex] -10(4s - 9t - 3) = -40s + 90t + 30 [/tex]
