you have to apply this formula (a+b)(c-d)=ac-ad+bc-bd
-6a^3*b*5a^2+6a^3b*2ab+6a^3b*b+2ab^2*5a^2-2ab^2*2ab-2ab^2*b=
-30a^5*b+12a^4b^2+6a^3b^2+10a^3b^2-4a^2b^3-2ab^3
Answer:
1.4*10^4
Step-by-step explanation:
move the decimal 4 places
Answer:
d ≤ - 7
Step-by-step explanation:
Given
- 38d - 57 ≥ - 19d + 76 ( add 19d to both sides )
- 19d - 57 ≥ 76 ( add 57 to both sides )
- 19d ≥ 133
Divide both sides by - 19, reversing the symbol as a result of dividing by a negative quantity.
d ≤ - 7
