A compound event, I believe
Responda:
11
Explicação passo a passo:
Área do retângulo = comprimento * largura
Dado
Comprimento = 4
Largura = 3x + 2
Área = 44
Substitua na fórmula e obtenha x
44 = 4 (3x + 2)
44 = 12x + 8
12x = 44-8
12x = 36
x = 36/12
x = 3
Obtenha os lados mais longos
Lado mais longo = 3x + 2
Substitua x = 3
Lado mais comprido = 3 (3) + 2
Lado mais comprido = 11
Portanto, a medida do lado mais longo deste retângulo é 11
Answer:
18 - 6y
Step-by-step explanation:
6(3 - y) ← multiply each term in the parenthesis by 6
= 18 - 6y
True.
The diameter is the axis of symmetry of a circle.
The diameter divides the circle into two equal parts. Therefore, it can be considered an axis of symmetry. Everything on the right of the diameter is the same as everything on the left of the diameter.
answer
True.
<h3>
Answer: They're all the same</h3>
====================================================
Reason:
means we have 6 copies of "2" multiplied out as shown in choice B. That explains how A and B are the same, and we can say
The parenthesis are optional, but I find they're handy to count the '2's easier.
----------------
Now notice that
So,
The last step is possible because we have two copies of 
multiplied together.
This shows that choice C is equivalent to A and B.
-------------------
Lastly,
The jump to the last step is possible because we have three copies of 
multiplied together.
This shows choice D is equivalent to the others.
All four expressions are the same.
They represent different ways to say the same number. That number being 64.
