Which of the following is the equation for x: ax^2 = bx? select all that apply.

1.) x = a
2.) x = b
3.) x = 0
4.) x = -b/a
5.) x = b/a
6.) x = ab

Step-by-step explanation:

ax^2=bx

ax^2-bx=0

x(ax-b) = 0

x=0 and ax-b=0 --> ax=b --> x = b/a

Thus x=0, and x=b/a (so, 3 and 5)

answer is 8x+24

area of vanessa's patio = length × width

given, length = (3x² + 5x + 10)

width = (x² - 3x - 1)

area of vanessa's patio = (3x² + 5x + 10)(x² - 3x - 1)

= 3x²(x² - 3x - 1) + 5x(x² - 3x - 1) + 10(x² - 3x - 1)

= 3x⁴ - 9x³ - 3x² + 5x³ - 15x² - 5x + 10x² - 30x - 10

= 3x⁴ - 4x³ - 8x² - 35x - 10

hence, expression of vanessa's patio = (3x⁴ - 4x³ - 8x² - 35x - 10)
