Answer:
x=4
Step-by-step explanation:
to get rid of the square root on the right you square both sides so
2x+8=x^2
Then bring
2x+8
to the left so you have 0=(x^2)−2x+8
Now you can do the quadratic formula to find the zeroes

26)68*
27)90*
28)90*

Answers. Brainliest in payment would be acceptable XD
Not sure what it means by "classify" But I'm assuming it just means name the shapes. If that's the case,
11 is a square, because all the inside lines are the same length, and all meet at 90 degree angles.
12 is a rectangle, because all the sides are parallel, but they are not congruent.
13, I've no idea.
I sincerely hope I helped, though I probably did not.
