Answer:
see explanation
Step-by-step explanation:
Given
x +
≤ - 3 or x - 3 > - 2
Solve the left and right inequalities separately, that is
x +
≤ - 3 ( isolate x by subtracting
from both sides )
x ≤ - 3 -
, that is
x ≤ -
-
, thus
x ≤ - 
OR
x - 3 > - 2 ( isolate x by adding 3 to both sides )
x > 1
Solution is
x ≤ -
or x > 1
2 is Reflexive property
4 is (I don't remember the specific property of this)
Answer: 1) The missing length is 40. 2) The missing side is 30 .
Step-by-step explanation:
1) 9^2 + b^2 = 41^2
81 + b^2 = 1681
-81 -81
b^2 = 1600
b= 40
2) 24^2 + 18^2 = c^2
576 + 324 = c^2
900 =c^2
c= 30
