230 because i think 20% is 200 and 23% is 230. hope this is right, if its wrong i,m sorry.
All you have to do in order to solve for the length of the square, simply take the expression and divide each term in the equation by 4, since the perimeter equation is the result of the length of the side equation multiplied by 4.
The final solution would be C.
It will increase by $30
We need to convert the percentage to a decimal by dividing by 100. Then we multiply by the $150.
150 x 0.20 = 30
(0, -2) and (1, 1) both work in this system of equations.
The best way to find if it is a solution is to look for those points on the graph. When you graph the point, it needs to fall in an area where both lines or shaded or on a solid line.
(0, -2) falls on a solid line.
(1, 1) falls in the double shaded area.
The answer would be option 1, mass divided by volume
