Answer:

m = 18

Step-by-step explanation:

Given :

=> -15 is a root of the polynomial

=> It is a zero to the solution.

Process :

Substitute -15 in place of x.

=> (-15)² + (-15)m + 45 = 0

=> 225 + 45 - 15m = 0

=> 15m = 270

=> m = 270/15

=> m = 18

Simplify sqrt 244x + sqrt 36x - sqrt 25x

Morgarella [4.7K]

First simplify the square roots: $2 \sqrt{61x}+6 \sqrt{x}-5 \sqrt{x}$
Then simplify the last two terms: $2 \sqrt{61x}+\sqrt{x}$
Since 61 is prime, you can't take a rational root out of it.

(2n-9)-(-2.4n+4) Please help!

Furkat [3]

Answer: =4.4n-13

Step-by-step explanation:

Let's simplify step-by-step.

2n−9−(−2.4n+4)

Distribute the Negative Sign:

=2n−9+−1(−2.4n+4)

=2n+−9+−1(−2.4n)+(−1)(4)

=2n+−9+2.4n+−4

Combine Like Terms:

=2n+−9+2.4n+−4

=(2n+2.4n)+(−9+−4)

=4.4n+−13
