Let's start by going left to right:
50000/50000 * 600 * 700.
50000/50000 cancels each other out so it's 1.
1 * 600 * 700.
600 * 700 = 420000
1 * 420000 = 420000
Sorry, the way this is written is a little confusing, but I’m assuming you mean the equation is x^2 + 18x + 12? Sorry if I’m mistaken. If this happens to be the case, then the a value would be 1, the b value would be 18, and the c value would be 12. Again I’m assuming this is in the ax^2 + bx + c formula. I hope this helps, sorry if I’m wrong :/
paint is needed to cover an entire wall : 2
if 1/2 gallon of paint cover 1/4 of a wall => 1 wall = (1/2)/(1/4) =2
52/38 = 1.368

Answer:
Use a matrix equation to solve the system of linear equations: -2x + 4y= 2, -3x+7y=7 *
