The building of the Blue Museum of Barcelona is triangular. Each side of the building is 180 m. How far do we have to travel to
Sever21 [200]

Answer:

540 m

Step-by-step explanation:

The building of the Blue Museum of Barcelona is triangular and each side of the building is 180 m.

This means the building is shaped as an equilateral triangle.

We need to find the total distance traveled if we go round the building, that is, its perimeter.

The perimeter of an equilateral triangle is given as:

P = 3L

where L = length of the side of the building = 180 m

The total distance traveled if we go round the building will be:

P = 3 * 180 = 540 m

We would need to go 540 m to travel around the building completely.

Given:
jekas [21]

Answer:

we conclude that:

If 4x - 6≠4, then 2x–5≠5 is the contrapositive of a conditional statement if 2x -5=5, then 4x-6=14.

Step-by-step explanation:

We know that the contrapositive of a conditional statement of the form "If p then q" is termed as "If ~q then ~p".

In other words, it is symbolically represented as:

' ~q ~p is the contrapositive of p q '

For example, the contrapositive of "If it is a rainy day, then they suspend the match" is "If they do not suspend the match, then it won't be a rainy day."

Given

p: 2x -5=5

q: 4x-6=14

As the contrapositive of a conditional statement of the form "If p then q" is termed as "If ~q then ~p

Thus, we conclude that:

If 4x - 6≠4, then 2x–5≠5 is the contrapositive of a conditional statement if 2x -5=5, then 4x-6=14.
