4√5x - √80x+√45x Help please

Mathematics
1 answer:
N76 [4]2 years ago
7 0

Answer:

Step-by-step explanation:

Remark

√80 =  √(16 * 5) = 4√5      I will put the - sign in when I gather terms

√45 = √(9 * 5) = 3√5

Expression

4√5x - √80x+√45x

Solution

4√5x - 4√5x  + 3√5x

The first two terms cancel out

3√5x is all that is left

Answer: 3√5x

A=15000(1+0.03*4)=$16800

For second case

A=15000(1+0.05*5)=$18750

Difference will be 18750-16800=$1950
