The first one: A shape is a rectangle if and only if the shape has exactly four sides and four right angles.
Step-by-step explanation:
The true statement is the first one:
A shape is a rectangle if and only if the shape has exactly four sides and four right angles.
<span>When flipping two standard American quarters, there are four independent possible outcomes:
-Tails, tails
-Heads, heads
-Heads, tails
-Tails, heads
Looking, then, at these four outcomes, there are three of those that include at least one head. As such, the answer to this question is three possibly different ways for her to achieve the desired outcome.</span>
The answer is true.
Really all you ever need is two points and you should find an equation.
Queremos encontrar el valor mínimo de x que es una solución para la inecación dada, veremos que es x = 4
<h3>
Trabajando con inecuaciones.</h3>
Lo primero que debemos hacer es aislar la variable x en un lado de la inecuación, partimos de:
5x - 2 ≥ 18
Sumamos 2 en ambos lados:
5x -2 + 2 ≥ 18 + 2 = 20
5x ≥ 20
Ahora dividimos ambos lados por 5:
5x/5 ≥ 20/5
x ≥ 4
Esto significa que x es mayor o igual a 4, de aqui podemos concluir que el valor mínimo que puede tomar la variable es x = 4.
