if you’re not paying 15%, then you’re paying 85%
(100-15 = 85)
so
.85 * 12 = 10.20
1/2*5 = 2.5 ~ 3 (round-off)
1/3* 10 = 3.33 ~ 3
Answer:
5

Simplify.
n=5 is a solution.
n = 5
12√18-6√20-3√50-8√45
<em>*Break each radical up into the product of a radical of a perfect square and a second radical*</em>
12(√9*√2)-6(√4*√5)-3(√25*√2)-8(√9*√5)
<em>*Simplify the radicals*</em>
12(3√2)-6(2√5)-3(5√2)-8(3√5)
<em>*Distribute*</em>
36√2-12√5-15√2-24√5
<em>*Combine like terms</em>*
21√2-36√5
