A square has 4 equal sides
use pythagroeas theorem since a square has 4 right angles
a^2+b^2=c^2
a=b because the sides are equal (11)
11^2+11^2=c^2
242=c^2
square root both sides
11√2=c
the diagonal legnth is 11√2 centimiters
Answer:
7
Step-by-step explanation:
If you divide 8y / 8 then you have to do the same thing to 56. When you do, y = 7
No solution
because delta ( b^2 - 4ac ) is lower than 0(zero) .
