Cole ate 2/3 of the cookies in the cookie jar. Jim ate 1/4 of the cookies

Answer:

Step-by-step explanation:

first, we start with 2 dozen = 2 * 12 = 24 cookies

next, cole eats 2/3 of the cookies

2/3 of the cookies = 2/3 * 24 = 16

we are then left with

original # - # of cookies cole ate = 24 - 16 = 8

next, jim eats 1/4 of the cookies left

cookies left = 8

1/4 of cookies left = 1/4 * 8 = 2

cookies left - cookies jim eats = cookies still in jar = 8 - 2 = 6

Answer:

1. (x+5)(x-1)

6. (3x+4)(x-6)

9. (x+5)(x-5)

Step-by-step explanation:

To factor an equation, break the polynomial into two binomials which multiply to make it. There are three main ways to factor:

Regular: Find two numbers that multiply to C and add to B from $ax^2 + bx + c$ .

$x^2+4x-5 = (x+5)(x-1)$

Grouping: Find two numbers that multiply to A*C and add to B. Then split B into the two factors and factor by GCF.

$3x^2-14x-24\\3x^2 - 18x + 4x - 24\\(3x^2-18x)+(4x-24)\\3x(x-6)+4(x-6)\\(3x+4)(x-6)$

Difference of Squares: Factor by taking the square root of each term. $a^2-b^2 = (a-b)(a+b)$

$x^2 - 25 = (x+5)(x-5)$
