True, because a parallelogram is a four-sided rectangular figure with opposite sides parallel.  This is a way to describe a rectangle as well.  The only difference is that rectangles must have 90 degree angles, but it is possible for a parallelogram to have 90 degree angles as well.  This also means that all rectangles are technically parallelograms as well.

We let x be the number of tickets that Sara and Jake sold individually. With this representation, the number of tickets sold by Cole is equal to 2x+6. 

(a) x + x + (2x + 6) = 538
The value of x from the generated equation is 133. 

(b) Sara sold a total of 133 tickets.

What is the value of a?
Sindrei [870]

Answer:

a=2

Step-by-step explanation:

Firstly, in order to simplify the expression, we should aim to combine the two terms given. In order to do this, both must have the same denominator. We can give them the same denominator by multiplying the second term -\frac{2}{x+2} by \frac{x+2}{x+2}. This way the fraction value remains the same but now has the same denominator as the first term:

-\frac{2}{x+2} *\frac{x+2}{x+2} \\\\=\frac{(-2)(x+2)}{(x+2)(x+2)} \\\\=\frac{-2x-4}{(x+2)^{2}}

From here we can now combine the two terms:

\frac{2x+6}{(x+2)^{2}} +\frac{-2x-4}{(x+2)^{2}} \\\\= \frac{(2x+6)+(-2x-4)}{(x+2)^{2}} \\\\\\=\frac{2x+6-2x-4}{(x+2)^{2}}\\\\= \frac{2}{(x+2)^{2}}

Therefore, a = 2.

Hope this helped!
