Answer:
-2x - 4
Step-by-step explanation:
Is your expression
-2 x x = -2x
-2 x 2 = 4
therefore, your expression would be:
-2x - 4
Answer:
a. 0 solutions b. infinite
Step-by-step explanation:
a. the two lines don't pass through each other therefore there is no solution b. the two lines are on top of each other ;) therefore there are infinite solutions.

Answer: Choice C) 9m^8</h3>
============================================================
Explanation:
Each side of the square is the same, so we have length = width in this case.
Length = 3m^4
Width = 3m^4
Area = (length)*(width) = (3m^4)*(3m^4) = (3*3)*(m^4*m^4) = 9m^8
Note how m^4*m^4 leads to m^8. We add the exponents.
The general rule is a^b*a^c = a^(b+c).
Answer:
0.853
Step-by-step explanation:
Use conditional probability. The probability of event A, given that event B has occurred, is:
P(A|B) = P(A and B) / P(B)
The probability that it is not raining, given that the flight leaves on time, is:
P(not raining | on time) = P(not raining AND on time) / P(on time)
P(not raining | on time) = 0.81 / (1 − 0.05)
P(not raining | on time) = 0.853
