Answer:
180 different four-course meals
Step-by-step explanation:
So you have one out of 3 salads, one out of 3 appetizers, one out of 4 entrees, and one out of 5 deserts. To find the number of meals that are possible, multiply 3 by 3 by 4 by 5
3 * 3 = 9
9 * 4 = 36
36 * 5 = 180
Use ac method
multiply 12 and -56
-672
now find what 2 factors of -672 add to -89
answer is -96 and 7
expand the middle term like that
12x²-96x+7x-56
group
(12x²-96x)+(7x-56)
factor
12x(x-8)+7(x-8)
undistribute the (x-8)
(x-8)(12x+7) is answer
