The left side of this equation is already a perfect square: <span>x^2-10x+25=35.
Rewriting it, we get (x-5)^2 = 35.
Taking the sqrt of both sides, x-5 = sqrt(35).
Solving for x: x = 5 plus or minus sqrt(35) (answers)</span>
Since the total is 42 divide by two since they are the same length so it would be 21
I don't think you can give medals on this site, but ok
a way to simplify it is to solve for y
x+2y=8
minus x both sides
2y=8-x
divide both sides by 2
y=4-x/2
(x,y)
just sub points in (sub x values for x and see if you get the coresponding y value)
example
point (8,0)
x=8 and the resulting y should eual 0
y=4-x/2
y=4-8/2
y=4-4
y=0
yes
A. (8,0) works, (6,1) works, (4,2) works
B. (2,4) doesn't work, so this option is wrong
C. (0,8) doesn't work, so this option is wrong
D. (0,8) still , doesn't work, so this option is wrong
answer is A
