hope it helps , make sure to follow !!!!
The length of AC is found using the Pythagorean theorem which is a^2+b^2=c^2.
In this case your equation would look like 4^2+4^2=c^2.
Four to the power of two is 16 so 16+16=c^2.
16+16=32
32=c^2
Root 32 = c
Length AC is root 32.
B) The lines intersect in two different points so the system has two solutions
