Simplify the expression: 4b - 24 + 19 4p - 5p - 30p 4.2v - 5 - 6.5v

1 answer:

4 0

For the first expression we will only simplify the constants:

4b - 24 + 19 ——> 4b - 5

The second expression only has variables so we simplify the whole expression

4p - 5p - 30p = -31p

The third expression we will only simplify the variables

4.2v - 5 - 6.5v ——> -2.3v - 5

18 factors into 2 * 3 * 3

Both factors have an a^2 under the root sign. The rule for that is take 1 a outside the root sign and throw the other one away.

The same rule applies to the two 3s that factor 18.

What you get is

3a√2 * 4*a*√3

Answer 12a^2 √2 * √3
