-12 + 9 - (-3) - 11
Remember PEMDAS: This is the order of operation.
P-Paragrahp
E-Exponent
M-Multiply
D-Divide
A-Add
S-Subtract
1st step: PEM
-(-3) is actually -1 * -3 = + 3
-12 + 9 + 3 - 11
2nd step: D is not possible, so we do A.
9 + 3 = 12
3rd Step: Subtract
12 - 12 - 11 = 0 - 11 = -11 CHOICE B.
50 percent is the probability
Answer:
-8
Step-by-step explanation:
-72 / 9 = -8
Correct, because the area of a square = side x side = side^2
<span>The slope of a line tells us how something changes over time. If we find the slope we can find the </span>rate of change<span> over that period </span>of change means.
