Step-by-step explanation:
29+1/5r=
29+(1/5×-1/2)
29+1/10
291/10
=29.1
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:
r =
Step-by-step explanation:
r=30√12,−30√12
Yes
No
Yes
No
This is because in order to be addition property of equality they have to add/ subtract by the same exact amount on both sides.
