(4x + 2)(x - 6) = 0
I need help with this math

Tomas is making trail mix using granola and walnuts. he can spend a total of $12 on the ingredients. he buys 3 pounds of granola that costs $2.00 per pound. the walnuts cost $6 per pound. he uses the equation to represent the total cost, where x represents the number of pounds of granola and y represents the number of pounds of walnuts. he solves the equation for y, the number of pounds of walnuts he can buy. answer- b tomas added 6 to both sides of the equation instead of subtracting 6. just took the test

Which equation represents a line that is parallel to the line whose equation is 3x-2y=7( show all work)

Which expression is equivalent to 3^3 + 2^2?
