What polynomial should be subtracted from the polynomial y^2–5y+1 to get the difference equivalent to:

4y^2–y+7
please explain

Good evening

Step-by-step explanation:

y² – 5y + 1 − P = 4y² – y + 7

then

P = y² – 5y + 1 − (4y² – y + 7)

then

P = y² – 5y + 1 − 4y² + y − 7

then

P = (y² – 4y²) − (5y − y) + (1 − 7)

then

P = -3y² − 4y - 6

:)

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.

step-by-step explanation:

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
