Factoring trinomials, mind me out?

(x - 13)(x + 3)

Step-by-step explanation:

The square term is just x^2 with no coefficient.

Write:

(x    )(x    )

Now you need two numbers that multiply to -39 and add to -10.

39 = 3 * 13

The numbers you need are -13 and 3 since -13 * 3 = -39, and -13 + 3 = -10.

Now write the numbers -13 and +3 in the parentheses.

(x - 13)(x + 3)

walter needs to make at least 5 more cookies but no more than 40. 5 ≥ x ≥ 40;

step-by-step explanation:

walter has to make a minimum of 20 cookies. he already has 15 cookies made, so he must make 5 more to meet the minimum.

the maximum amount of cookies he can make is 55. he already has 15, so he has to make no more than 40 more cookies to meet the maximum.

you probably already have the answer but anyways it's b. 15.0
