Find the product: (x² - x + 1)(2x² + 3x + 2).
Tresset [83]

Answer:

(2x^3-2x^2-12x) is the required product.

Step-by-step explanation:

The given equation is:

2x(x-3)(x+2)

Solving the above given equation, we get

=(2x^2-6x)(x+2)

which can be written as:

=(2x^3-6x^2+4x^2-12x)

Solving the like terms, we get

=(2x^3-2x^2-12x)

which is the required product of the given expression.

Use distributive property to write an expression that is equivalent to each expression. -8(-x-3/4y+7/2
Lesechka [4]

Answer:

  8x +6y -28

Step-by-step explanation:

The outside factor applies to each inside term, so the equivalent expression is ...

  -8(-x -3/4y +7/2) = 8x +6y -28

Applying the distributive property once again, we can also write the equivalent expression ...

  = 2(4x +3y -14)

__

There are an infinite number of other equivalent expressions. The problem statement is non-specific as to the acceptable form.

You are going to model the population size of a species of bird that is gradually becoming extinct. Which graph is the BEST choi
kvasek [131]
Hey Jay,
Since we can't see the graphs, we can't be entirely sure, but given that we are trying to model the population size of a species of bird that is slowly going extinct. I would say the best graph would be a line graph. Line graphs show changes over time so this would be the best graph to use. Hope this helped!

Cheers,
Izzy
