The perimeter formula is 2 times length plus 2 times width.
2(x+3)+2(x)=24
Distribute.
2x+6+2x=24
4x+6=24
Subtract 6 from both sides.
4x=18
x=2
So the length is 5 and the width is 2

Write the set { 1, 3, 7, 15, 31, 63 } in set builder form

Sholpan [36]

Answer:

{ x : x = 2^n -1 , n ∈ N}

Where N is the set of natural numbers

Step-by-step explanation:

Mathematically, we can rewrite each term in the set as follows;

1 = 2^1 - 1

3 = 2^2 -1

7 = 2^3 -1

15 = 2^4-1

31 = 2^5-1

63 = 2^6 -1

so we can conclude that the nth term is 2^n -1

So writing this in set builder notation, we have;

{ x : x = 2^n -1 , n ∈ N}

Where N is the set of natural numbers

Answer:

d) The points on the perpendicular bisector of a side of a triangle are equidistant from the vertices of the side it bisects.

Step-by-step explanation:

By the property of perpendicular bisector, any point on the perpendicular bisector is equidistant from the end points of the segment it bisects.

For the given triangle any point on the line $CD$ is equidistant from the vertices $A$ and $B$ as line $CD$ is the perpendicular bisector of side $AB$ .
