Which is a factor of 6x2y + 8x2 – 30y – 40 ?

1 answer:

5 0

If you would like to find a factor of 6x^2y + 8x^2 - 30y - 40, you can calculate this using the following steps:

6x^2y + 8x^2 - 30y - 40 = 2x^2 * (3y + 4) - 10 * (3y + 4) = (3y + 4) * (2x^2 - 10) = 2 * (3y + 4) * (x^2 - 5)

The correct result would be 3y + 4.

Answer:

Step-by-step explanation:

equation of the line graphed

(y-4)/(2-4) = (x+6)/(0+6)

(y-4)/(-2) = (x+6)/6

y-4 = (x+6)/-3

y = (x+6)/-3 +4

y = (x+6-12)/-3

y = -1/3x + 2

so the answer is A

A cube has a side length of x feet. Which expression represents the surface area of the cube?

alexdok [17]

The answer is D)6x2 square units.

A surface area of a cube is a sum of its sides' areas. A side of the cube is a square, and there are total 6 sides of the cube. Also, an area of the side of the cube is the area of the square, which can be expressed as a², where a is the length of the side. Therefore, the surface area (SA) of the cube is:
SA = 6*a² = 6a²

If side length is x, that means that a = x units.
After replacing it in the formula, you will have:
SA = 6a² = 6x² square units
