Answer:

C

Step-by-step explanation:

Mean is the average. To find mean, add all the numbers in a data set, then divide by the number of values.

Example: 1,2,3,4,5

Mean: 1+2+3+4+5= 15

Number of values: 5

15/5 = 3

Mean is 3

skad [1K]

Answer:

D

Step-by-step explanation:

We want to find:

(x^2+2x-3)(4x^2-5x+6)

Distribute:

=(x^2+2x-3)(4x^2)+(x^2+2x-3)(-5x)+(x^2+2x-3)(6)

Distribute:

=(4x^4+8x^3-12x^2)+(-5x^3-10x^2+15x)+(6x^2+12x-18)

Rearrange:

=(4x^4)+(8x^3-5x^3)+(-12x^2-10x^2+6x^2)+(15x+12x)+(-18)

Combine like terms:

=4x^4+3x^3-16x^2+27x-18

The answer is D.
