PLEASE ANSWER! When a trinomial is factored as (x+m)(x+n), what is the sum of m and n?

1 answer:

5 0

C. The coefficient of the x-term of the trinomial

Again, here's your reason:
(x+m)(x+n)
x^2 +xm+nx +mn
x^2 + x (m+n) + mn

As you can clearly see that the sum of m and n equal the coefficient of x term so, the correct option is C.

3 people work full time together on a project, but their total time on the project is to be equivalent to only 1 person working

NikAS [45]

Let x = the amount of time that the third person needs to work on the job to add up to one

1 = 1/2 + 1/3 + x

1 - 1/2 - 1/3 = x

To subtract the fractions we need to put them all over a common denominator. Let's use 3*2 = 6 as the denominator; so 1 = 6/6, 1/2 = 3/6, 1/3 = 2/6:

6/6 - 3/6 - 2/6 = x

1/6 = x

The third person must work 1/6 time on the project.

Answer:

The three angles form a "linear triplet" , so their measures must add up to $180^o$

Step-by-step explanation:

Notice that the three angles add up to cover half a circle (therefore 180 degrees of angle. Such type of angle combination is called a "linear triplet" since they add up to give a straight line.
