The shaded region in the graph is the solution set for which inequality? A) 4x + 5y ≤ 20 B) 4x + 5y ≤ -20 C) 5x + 4y ≤ 20 D) 5x + 4y ≤ -20

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0

step-by-step explanation:

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.

yes.. it's proven to be 36.
