The median is the middle number, the range is the difference between the lowest and highest values(subtract the lowest number from the highest number) and the mode is the number that appears most often in a set of numbers

Answer:
2
Step-by-step explanation:
Given
f(x) =
x²
To evaluate f(- 2), substitute x = - 2 into f(x)
f(- 2) =
× (- 2)² =
× 4 = 2
Answer:
Step-by-step explanation:
1) the equation would be:
(2x+4)x(5x+1) because if the amount of ballpens are (2x+4) and the ballpens are $(5x+1) each, you would multiply them.
this is the expanded version of (2x+4)(5x+1)
{10x^2 + 2x + 20x + 4
10x^2 + 22x + 4}
2) (x^2 +1)(x+2) are multiplied to find the volume of the box
So when expanded it looks like this:
{x^3 + 2x^2 + x + 2}
3) (15a^2b^3) would be multiplied with (2a). This is because to find the total you would times the numbers.
so when expanded:
(15a^2b^3)(2a)
{(15a^3)(2ab^3)}
4) 5X(x+8)=33
5x+40=33
5x=33-40
5x=-7
X= -7/5
5) x-8=8x
8x-x = -8
7x=-8
X=-8/7
