Use any method to find the product
(x + 7)(x - 3)

x^2 +4x-21

Step-by-step explanation:

Just expand using FOIL (First, Outside, Inside, Last, I believe)

(x + 7) ( x - 3)  = x² + 4x - 21

Step-by-step explanation:

Using the FOIL method: (a + b) (c - d) = ac - ad + bc - bd

(x + 7) ( x - 3)

= x² - 3x + 7x - 21

Add like terms:

= x² + 4x - 21

Therefore, the product of the two binomials is: = x² + 4x - 21

8

step-by-step explanation:

to find the amount of gift bags to use all the supplies, find the gcf or greatest common factor. this is the largest number which multiplies evenly into each term.

48 has factors: 1, 2, 3, 4, 6, 8, 12. 16, 24, 48

80 has factors: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80

64 has factors: 1, 2, 4, 8, 8, 16, 32, 64

the highest number factor they all share in common is 8. this means there will be 8 bags with 6 pencils, 10 markers, and 8 stickers in each bag.

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0
