(–7w2 – 2w – 1) – (–5w2 + 3w – 2)

-14w²-7w+1

Step-by-step explanation:

(–7w2 – 2w – 1) – (–5w2 + 3w – 2)

-14w²-2w-2w-1 +10w²-3w+2

combine the like terms

-14w² + 10w² - 2w-2w-3w+2-1

-4w²-7w+1

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

the probability that a bird is green (.30) is true
