Answer:

x² + x + 1 + 2/(x - 1)

Step-by-step explanation:

(x³ + 1) / (x - 1) =
(x³ - 1 + 2) / (x - 1) =
(x³ - 1)/(x - 1) + 2/(x - 1) =
(x - 1)(x² + x + 1)/(x - 1) + 2/(x - 1) =

1615/170 simplify show work

Sloan [31]

1615/170

We first need to convert this into a proper fraction. Which means that the denominator must be larger than the numerator for it to be proper. Also, since 1615 is BIGGER than 170, we will end up with a mixed fraction. A mixed fraction always has a whole number.

1615 can go into 170 how many times?

9 times

170*9 = 1530

Now subtract.

1615 - 1530 = 85

Now we have our mixed fraction: 9 85/170

Now we must simplify the fraction.

85/5 = 17
170/5 = 34

17/34 is the smallest possible fraction we can get.

9 17/34

Final answer: $9 \frac{17}{34}$

Mr. Gaster has $5 in his piggy bank and wants to put $45 every week into the piggy bank. Make you equation showing how much mone

Romashka-Z-Leto [24]

So your starting amount is 5. Your equation will start like this:
5+
Now 45 dollars a week. So no matter how many weeks you are going to multiply it by 45. So you add that in and you have an equation that looks like this:
5+45x
X stands for the weeks. Then finish it off with your equals:
5+45x=y
Y is the total amount of money.
The Equation will be.
5+45x=y

Part 2:

The equation is set up on weeks so you need to find out how many weeks 28 days is.
28/7=4

Now that you know that you can substitute 4 for x.

5+45*4=y
5+180=y
185=y
He will have 185 dollars in his bank. <span />

Triangle PQR has sides measuring 9 feet and 10 feet and a perimeter of 24 feet. What is the area of triangle PQR? Round to the n

gregori [183]

Answer: 22 square feet

Step-by-step explanation:

Using Heon's formula, the are can be found with:

$= \sqrt{s(s - a)(s - b)(s - c)}$

Where s is half the perimeter

a, b and c are sides

Perimeter = a + b +c

24 = 9 + 10 + c

c = 24 - 9 - 10

c = 5 feet

s = 24 / 2 = 12

Area

$= \sqrt{s(s - a)(s - b)(s - c)}\\\\= \sqrt{12(12 - 9)(12 - 10)(12 - 5)}\\\\= \sqrt{12 * 3 * 2 * 7}\\\\\\= \sqrt{504} \\\\$

= 22 ft²
