Answer:
Step-by-step explanation:
The question is to simplify the expression 
First, we can eliminate the 2nd parenthesis expression by changing signs of all the terms since there is a "-" sign in front. Then we add the "Like Terms". The process is shown below:
The first answer choices (has some typos) is correct. The correct answer is
Do what? If you mean to find when it equals zero...
By inspection you can see that if x=0 or 2 the expression is equal to zero...
You multiply each term in the parentheses by the term outside the parentheses...like:
3x*3x+3x*6 which is equal to:
9x^2+18x If you meant to expand it....
9x(x+2) If you meant to factor it completely
The correct answer to this question is letter "<span>B. We can't determine from the given information."
</span>
Using the information as stated, "<span>If j and k are intersecting lines, A and B are points on j, and C and D are points on k," the number of planes that contain points A, B, C, and D cannot be determined because of the lack of information.

Answer:
1/16
Step-by-step explanation:
Possible outcomes when rolling a fair die = 1, 2, 3, 4, 5, 6 (i.e 6 possible outcomes)
Possible outcomes when rolling an even number = 2, 4, 6 (i.e 3 possible outcomes)
Hence P (rolling even number on 1 roll) = 3 / 6 = 1/2
P (Rolling 4 even numbers on 4 rolls) = (1/2)(1/2)(1/2)(1/2) = 1/16
Multi ting a number is like adding the number that many times.
Repeated addition would be adding 3/4 to itself 4 times:
3/4 + 3/4 + 3/4 + 3/4 = 12/4 = 3
Then multiplication method:
3/4 x 4 = 12/4 = 3
