Answer:
2 sqrt(15) + 3 sqrt(10)
Step-by-step explanation:
sqrt(6) * ( sqrt(10)+ sqrt(15))
Distribute
We know that sqrt(a) sqrt(b) = sqrt(ab)
sqrt(6) sqrt(10)+ sqrt(6) sqrt(15))
sqrt(60) + sqrt( 90)
sqrt( 4*15) + sqrt(9*10)
We know that sqrt(a) sqrt(b) = sqrt(ab)
sqrt(4) sqrt(15) + sqrt(9) sqrt(10)
2 sqrt(15) + 3 sqrt(10)
Needed discount= 350-220= 130
needed dicount %=(130/350)*100=37.14 %( this is minimum discount needed)
since only multiples of 5% are allowed ,the closest minimum discount is 40%.
(r^9 - s^10) (r^18 + r^9 s^10 + s^20)
Hope this helps
Answer:
1. Distributive Property
2. Addition Property of Equality
3. Multiplicative Property of Equality
Step-by-step explanation:
1. The 3 is multiplied by each number in the parenthesis
3*10=30
3*2=6
So 3*(10-2x)=30-6x
2. The 30 is subtracted from both sides
30-6x-30 = -6x
6-30 = -24
30-6x-30=6-30
So -6x=-24
3. The -6 is divided from both sides
-6x/-6 = x
-24/-6 = 4
-6x/-6 = -24/-6
So x=4
