First distribute the 3 so you'll have:

12+12x=12x+12

Next you subtract 12 from both sides and you'll get:

12x=12x

then you divide both sides by 12 and you get:

x=x

Problem: 3(4+4x)=12x+12

The first thing that you need to do is distribute 3(4+4x).

12+12x=12x+12

Subtract 12x from both sides.

12=12

This means that the equation has infinitely many solutions.

I hope this helps you :)

What length is the shorter leg of a right triangle that has hypotenuse 50 in long and its perimeter is 112 inches?
Brut [27]
The length of the shorter leg is 14 inches.

We will set up two equations for this; first, for the perimeter.  We will call the legs a and b:

a + b + 50 = 112

Subtract 50 from both sides:
a + b + 50 - 50 = 112 - 50
a + b = 62

We will isolate a, so we can use substitution.  Subtract b from both sides:
a + b - b = 62 - b
a = 62 - b

Now we will set up our Pythagorean theorem equation:
a² + b² = 50²
a² + b² = 2500

We will substitute our value for a from the first equation into this one:
(62-b)² + b² = 2500
(62 - b)(62 - b) + b² = 2500

Multiplying the binomials, we have:
62*62 - b*62 - b*62 -b(-b) + b² = 2500
3844 - 62b - 62b + b² + b² = 2500

Combining like terms:
3844 - 124b + 2b² = 2500

To set it equal to 0 and solve, we subtract 2500 from both sides:
3844 - 124b + 2b² - 2500 = 2500 - 2500
1344 - 124b + 2b² = 0

In standard form, we have
2b² - 124b + 1344 = 0

Using the quadratic formula, 
\frac{--124\pm \sqrt{(-124)^2-4(2)(1344)}}{2(2)}
\\
\\=\frac{124\pm \sqrt{15376-10752}}{4}
\\
\\=\frac{124\pm \sqrt{4624}}{4}=\frac{124\pm 68}{4}=\frac{124+68}{4}\text{ or }\frac{124-68}{4}
\\
\\=\frac{192}{4}\text{ or }\frac{56}{4}=48\text{ or }14

The shorter leg is 14 and the longer one is 48.

Find the missing value 3/8 = _____ to 72
Morgarella [4.7K]

Answer:

27

Step-by-step explanation:

First, you need to find the factor that coverts 8 to 72. I look as these problems as 3 to x and 8 to 72. To do this, divide 72 by 8, and that's what you'd multiply 3 with.

72/8 = 9

9 x 3 = 27

Watch day about 75,000 people visit Paris, France. Use commutative property to write two equivalent expressions that could be us
Studentka2010 [4]

Answer:

5\times 75,000 and 75,000\times 5

Step-by-step explanation:

We have been given that about 75,000 people visit Paris, France. We are asked to write two equivalent expressions that could be used to find the number of people that visits over a 5- day period .

To find the number of people over a 5-day period, we will multiply 75,000 people by 5 as:

\text{Number of people that visits over a 5-day period}=75,000\times 5

Commutative property of multiplication states that we can multiply numbers in any order.

Upon switching the order while multiplying, we will get:

\text{Number of people that visits over a 5-day period}=5\times 75,000

Therefore, our required equivalent expressions would be 5\times 75,000 and 75,000\times 5.
