Answer:
a²(b² - 2b) = a²b² - 2a²b
- a²(b² - 2b) is odd but -2a²b is the even number
=> a²b² must be the odd (because an odd number minus an even number equals an odd number)
=> a and b are odd (proven)
Answer:
11
Step-by-step explanation:
Since why is 5 you would do 5×2+1
Answer:
For these types of problems, You must look at the coefficients and variables separately and find the GCF for each. Then, combine the two
First, take 12 and 9
Factors of both
9- 1, 3, 9
12- 1, 2, 3, 4, 6, 12
So the gcf of 12 and 9 is 3
Now do the variables a and a^2
a^2 is just a twice
The GCF is a
Now combine a and 3
Answer: GCF is 3a
Answer:
x=-2
Step-by-step explanation:
If the question is asking for the intersection point, the answer is x=-2 or (-2,1) depending on if the teacher is asking for the intersection or value of x where it itersects
If the question is asking what the equation of the parabola is I would guess it is (x+1/2)^2 -4
I say go with x=-2 though
96/4=24 so the length of a standerd paralleegram is 24
