7(1•30) =1470
Explanation:
The ratio needs to be turned into a fraction. So we write 2:3 as 2/3. Since it can’t be reduced any further the answer is 2/3.
Answer:
4c^2 - 3a^2 -7ac +6bc -ab
Step-by-step explanation:
solve first 3a( a + b + c) - 2b ( a+ b +c)
which is = 3a^2 + 3ab + 3ac - 2ab - 2b^2 -2bc
there for 4c(-a + b +c) -( 3a^2 + 3ab + 3ac - 2ab - 2b^2 - 2bc)
= -4ac-3ac +4bc+2bc -3ab+2ab + 4c^2 -3a^2
=4c^2 - 3a^2 -7ac +6bc -ab
1 4 is 1 away from 5 5 is one away from 6 and It just goes on
6^-3 / 6^5
= 6^(-3-5)
= 6^-8
= 1 / 6^8
