Circle the first term in the trinomial, multiply it by each term in the binomial, and place each result in the blank spaces provided. Repeat this process for the second and third terms of the
trinomial until all of the spaces are filled in. Finally, in the space provided beneath the blanks,
simplify the expression by combining like terms and arranging the terms from highest to
lowest order. Show your work. (4 points)
(3x2 - 2x + 7)(x2 + 2x)

3x^4 + 4x³+ 3x² + 14x

Step-by-step explanation:

first term in the trinomial: 3x²

3x²*x² = 3x^4

3x²*2x = 6x³

second term in the trinomial: 2x

-2x*x² = -2x³

-2x*2x = -4x²

third term in the trinomial: 7

7*x² = 7x²

7*2x = 14x

Adding all terms, we get:

3x^4 + 6x³ - 2x³ - 4x² + 7x² + 14x

And ombining like terms:

3x^4 + 4x³+ 3x² + 14x

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204

step-by-step explanation:

i'm pretty sure it would take 20 hours because it's half the men so you multiply the number of hours it takes by 2
