Answer is x=31
125+132+72+x=360
329+x=360
x=31
X+y=2
y=1/2x+5
x+ y=2
-1/2x+y =5
Subtracting the two equations;
3/2x=-3
x=-2
Replacing in the first equation;
-2+y=2
y=4
They would intersect at (-2, 4)
Yes c would work best here
√3 x √5 = √15
7√15 - 2√15 = answer 5√15
simple
6² = 36
7² = 49
8² = 64
√64
