Answer:   x+1-\dfrac{3}{x-1}

<u>Step-by-step explanation:</u>

You can use long division or synthetic division.  Whichever method you choose, remember to include a zero for the missing term (0x)

Synthetic division:         x - 1 = 0   -->   x = 1

1 |\ \ 1\quad 0\quad -4\\.\ |\underline{\ \downarrow \quad 1\qquad 1}\\.\quad 1\quad 1\quad \boxed{-3}\quad \leftarrow \text{Remainder}\\\\\\=x + 1 + \dfrac{-3}{x-1}

Long Division:

.\qquad \underline{\ \ x+1\qquad \ }\\x-1)x^2+0x-4\\.\qquad \underline{-x^2+1x}\ \ \downarrow\\.\qquad \qquad \quad 1x-4\\.\qquad \qquad \quad \underline{-x+1}\\.\qquad \qquad \qquad \ \ \boxed{-3}\quad \leftarrow \text{Remainder}\\\\\\=x + 1 + \dfrac{-3}{x-1}

Belle's Cupcakes recently sold 6 pistachio cupcakes and 8 other cupcakes. Considering this data, how many of the next 56 cupcake
VikaD [51]

Answer: 24 pistachios cupcakes.

Step-by-step explanation:

We know that:

They recently sold 6 pistachio cupcakes and 8 other cupcakes.

Then we can model this with the ratio 6:8

This means that for each 6 pistachio cupcakes sold, they also sell 8 of another type of cupcakes.

Whit this info, if they sell 56 cupcakes, how many of them will be pistachio cupcakes?

Using the ratio above, we must find a number N such that:

N*6 + N*8 = 56.

N*(6 + 8) =  56

N*14 = 56

N = 56/14 = 4.

This means that:

out of the 56 cupcakes, 4*6 = 24 are pistachios cupcakes

                                        4*8 = 32 are other cupcakes.

Then you should expect that 24 out of the 56 cupcakes are pistachios cupcakes.
