Answer:
Step-by-step explanation:
a. A' means the complement with respect to Z? If so, then
To know A' you need to write all the elements in Z that are not in A.
b. All the subsets of B, is knowed as P(B),
c. (Add to A the elements of B, or equivalently add to B the elements of A)
d. express informally speaking the elements that have in common, but there is no element in common, so
|-1| = 1
|2| = 2
2+1 = 3
the total distance is 3
We have an isosceles triangle:
The length of the sides are:
side₁=side₂=x
side₃=(x+x)-3=2x-3
Perimeter of a triangle=is the sum of the all sides.
we have this equation:
x+x+(2x-3)=29
4x=29+3
4x=32
x=32/4
x=8
The length of the third triangle will be: 2x-3=2*8-3=16-3=13
Answer: The length of the longest side of the triangle would be 13 meters.
