Combine these terms: 8p + 6x + 21 - 2x + 9p
17p + 4x + 21
100
Use the distributive property to simplify: 3(x + 5)
3x + 15

Solve for x: x/6 = 6
x = 36

Can I use the distributive property on these equations? why? 1. 8(x-8) 2. 8x - 8
1. yes- everything inside the parentheses is simplified as much as possible. The next step in PEMDAS is multiplication. 2. no, there are no parentheses that need distribution.

What are the like terms
(1) 4x^2, 4x, x (2) 26, x, 8x^2
200
Use the distributive property to simplify: 8(x - 6) + 14
8x - 48 + 14 8x - 34

3x = 18
x = 6

What is the definition of "like terms"
Terms that have same variable to the same power
300
Use the distributive property to simplify: 4(2x + 10) - 20
8x + 40 - 20 8x + 20
300
5x - 15 = 90
5x = 105 x = 21
300
simplify: 2x (x + 7) -8
2x^2 + 14x -8

What is a constant? Bonus: what is a coefficient
Constant: number without a variable Coefficient: number that comes before a variable
400
10(9 - 3x) - 5x + 12
90 - 30x - 5x + 12 90 - 35x + 12 102 - 35x
400
-10x - 18 + 2x = 9x - 14
32 = x

what is x^2 * x^5
x^7
500
combine the like terms x^2 + 7x^3 - 9x +10 +3x^3 - 7x^2
x^2 -7x^2 -9x +10 3x^3 + 7x^3
500
Use the distributive property to simplify: -5(8 - 3x) - 9x + 40 + 7x
-40 + 15x - 9x + 40 + 7x 6x + 7x - 40 + 40 13x + 0 13x
500
90x - 4 = 10x - 20 + 16x/4
76x = -16 x = -16/76
