Answer:

350

Step-by-step explanation:

P(x) = 8 + 7x – 10x² = -10x² + 7x +8

The coefficient of x² is -10, the parabola has a maximum

x(max) = - (7 / 2 x (-10)) = 7 / 20

speakers should sold: 1000 x 7/20 = 350

Clara found the product of 3 – 6y2 and y2 + 2. Her work is shown below. (3 – 6y2)(y2 + 2) = 3(y2) + (–6y2)(2) = 3y2 – 12y2 = –9y
vladimir2022 [97]

Answer:

No, She did not use the distributive property correctly.

Step-by-step explanation:

While multiplying (3-6y^2)(y^2+2), he did not use distributive property correctly. She only multiplied 3 with y^2 and not with 2. Also she multiplied -6y^2only with 2 and not with y^2.
