Answer: 4=-2x -1 and y=-1 2x
Ok, so the quadratic coefient is 1, so great
take 1/2 of the linear coefient and square it
10/2=5, (5)^2=25
add that to both sides
x^2+10x+25=7+25
factor perfect square trionomial
(x+5)^2=32
squaer root both sides
x+5=+/-4√2
minus 5
x=-5+/-4√2
x=-5+4√2 and -5-4√2
P=44.6
P=a+b+√a^2+b^2=11+15+√11^2+15^2≈44.6
If it is 90 degreees at the angle
