1. An agency promo charged 15,000.00 for a 3-day and 2-night tour in Macau and
20,000.00 for the same tour with a side trip to Hong Kong. Ten persons joined
the trip, which enable them to collect 170,000.00. How many tourists made a
side trip to Hong Kong?​

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
