Answer: the answer to this question is a triangle.
Step-by-step explanation:
If you sliced the pyramid to the base there would still be a triangle left.
Answer:
Should be 1/2, or 0.5
Step-by-step explanation:
The mean is the average, so we divide the sum of the numbers(-1+0+1+2=2) by the quantity(4).
From the second equation y=-1-x so we can write -2x²+3x-1=-1-x.
So -2x²+4x=0, 2x(-x+2)=0, therefore x=0 or 2 and the corresponding y values are -1 and -3.
We can write the answers as ordered pairs (0,-1) and (2,-3).
You just need to equate the expressions to find the values for a,b and c. First, let's settle that 2^5/4=8, and 8 is 2^3. Also, an important tool here is the indicie rule:

1st expression: 2^5/4=8
2nd expression: It tells us that 2^5/2^a=2^3 (I know that this equals to 8 as all the expressions are equal therefore is the same as our first expression). Using the indicie law, this means that a=2
3rd expression: 2^b must equal to 8 as well, so b=3
4th expression: c=8 as all of the other expressions we have figured out equal to 8
So a=2, b=3 and c=8
To find the greatest common factor you take each number and write its prime factorization, then you identify the factors common to each number and multiply those common factors together <span />
