Which of the following is an expression?
2x = 10
n3-64
x > 9x + 7
n3-64
x = 3
9 + 3x
18
Distribute the outside term and rewrite (DO NOT SOLVE):
3(2x - 5y)
3(2x) + 3(-5y)
x = 3
x2 - 7
(3)2 - 7 = 2
Fully Factor 18.
2 * 3 * 3
Fill in the blank for the Multiplication Rule:
Negative times negative equals to __________.
Positive times negative equals to __________.
Negative.
y = -3
4 + 5y
-11
Distribute the outside term and rewrite (DO NOT SOLVE):
3a(2x2 - 8y)
3a(2x2) + 3a(-8y)
y = -4
-10 + y2
-10 + (-4)2 = 6
Fully Factor 24.
2 * 2 * 2 * 3
-5 - 3
What is the rule here? Adding or Subtracting? (Pay attention to the signs)
Adding, because same signs ADD
a = -3 b = 4
a + 2b
5
Distribute the outside term and rewrite (DO NOT SOLVE):
4ab(a + 2b - 3)
4ab(a) + 4ab(2b) + 4ab(-3)
j = -2 k = 5
-3k + j2
-3(5) + (-2)2 = -11
Fully Factor 40.
2 * 2 * 2 * 5
No need to solve: Will the answer for the following expression be NEGATIVE or POSITIVE?
(-3)8
Positive
x = -3 y = -5
- x + 2y
Distribute the outside term and rewrite (DO NOT SOLVE):
-2p(6q - 3r + 1)
-2p(6q) + -2p(-3r) + -2p(1)
a = -10 b = 5
2b - 3a2
2(5) - 3(-10)2 = -290
Simplify this fraction: (FACTOR first, then cancel out the shared number on top and bottom)
18/12
3/2
No need to solve: Will the answer for the following expression be NEGATIVE or POSITIVE?
-(-7)4
Negative
x = 3 y = 1 z = -4
2y - 3x - 2z
1
Distribute the outside term and rewrite (DO NOT SOLVE):
-5xy(2j - k - 12xyz)
-5xy(2j) + -5xy(-k) + -5xy(12xyz)
-3x2 + 4y3
-3(3)2 + 4(-2)3 = -59
Simplify this fraction: (FACTOR first, then cancel out the shared number on top and bottom)
14/42
1/3
