x + (x + 3) + x^{2} = 75

so you will add up all of the x 's but NOT the x^2

2x + 3 + x^{2} = 75

Rearrange to put the x^2 in front of 2x

x^{2} + 2x + 3 = 75

subtract the 75 from both sides

x^{2} + 2x - 72 = 0

Find the area. plzz help​
12345 [234]

The square has a side length of 9.

The area of the full square would be 9^2 = 9 x 9 = 81 square cm.

The area of the triangle is 1/2 x 4 x 3 = 6 square cm.

The area of the shape = 81 -6 = 75 square cm.

9/11 - 1/2 in it's simplest form​
Murrr4er [49]

Answer:

7/22

Step-by-step explanation:

Step 1: <u>Define/explain.</u>

To subtract fractions with different denominators, you must first find the least common denominator (LCM).

You can do this by listing the multiples of each denominator.

Step 2: <u>Solve.</u>

11: 11, 22, 33, 44, 55, 66, 77, 88, 99, 110

2: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22

22 is the LCM.

Now, we change the fractions to where they both have denominators of 22.

**REMEMBER: WHICHEVER NUMBER YOU MULTIPLY THE DENOMINATOR BY, YOU MULTIPLY IT BY THE NUMERATOR AS WELL!!**

9/11*2/2=18/22

1/2*11/11=11/22

Now, subtract as normal.

18/22-11/22=7/22

7/22 (simplified).

Step 3: <u>Conclude.</u>

Therefore, 9/11 - 1/2 = 7/22.

The function p(x) = 25x represents the number of pages p(x) a printer can print in x minutes. How many pages can the
Rashid [163]

Answer:

7,500 Pages

Step-by-step explanation:

So this printer can prink 25 pages in 1 (x) minute.

There are 60 minutes in an hour and we are waiting 5 hours, so 5x60 = 300 minutes.

Then you take the 300 and plug it in for x because that is how many minutes we are waiting for.  Now your equation should look like this:

p(x) = 25(300)

Next you multiply 25 x 300 and you get 7,500 pieces of paper
