Answer:
b option im not sure but
Step-by-step explanation:
A. 15-35=-20
b. -2+7=5
c. -10+14=4
d. 60-100=-40
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
There are no real solutions to solve Z. If there may be a typo or something, there are no solutions.
1)
x+10<-7
bring 10 to the other side
x<-10-7
x<-17
2)
-3x-4>5
bring -4 to the other side
-3x>9
divide -3 at the other side, since it is negative it changes to less than
x<-3
