Answer:

A = 3x^2 - 3

   ---------------

          2

Step-by-step explanation:

If the perimeter is 56 cm..

x - 1 + 3x + 3x + 1 = 56

7x = 56

x=8

The x - 1 side = 7

The 3x = 1 side - 25

The ex side = 24

The area of a triangle = base time height divided by 2.

So...

x-1 times 3x divided by 2 is your equation.

3x(x - 1) = 3x^2 - 3

A = 3x^2 - 3/2

Hope this is correct!!!

Answer:

See below.

Step-by-step explanation:

The reason a number divided by zero is undefined is as follows.

Every operation, addition, multiplication, subtraction, and division, is carried out between two numbers and must have a single correct answer.

For example 1 + 5 = 6. The only correct answer to 1 + 5 is 6. There is no other correct answer to that addition. The same is true of any multiplication, subtraction, or division. Another example: 8/2 = 4. No other correct solution exists to the division of 8 by 2 other than 4.

Division is defined in terms of multiplication.

The definition of dividing a number by another number is:

a divided by b equals c if and only if b * c = a.

For example, 10/5 = 2 if and only if 5 * 2 = 10. 5 * 2 does equal 10, so it is correct that 10/5 = 2.

Now let's try dividing by zero and see the problem that arises.

Let's try to divide 8 by 0.

8/0 =

Since we are not used to dividing by zero, we don't really know what the answer should be, but we can try different answers.

Let's say 8/0 = 8

Then by the definition of multiplication, we need 0 * 8 to equal 8, but we know that 0 * 8 = 0, so the answer of 8/0 cannot be 8. Let's try a different answer.

8/0 = 0, then we need 0 * 0 to equal 8, but 0 * 0 = 0, not 8, so 0 also does not work.

We can generalize and try

8/0 = k, but then that requires 0 * k to equal 8. Since multiplication by 0 always has a result of 0, there is no number k that will multiply by 0 and give 8. This means that a number divided by 0 cannot give a result.

Now let's try one more thing.

What about 0 divided by 0.

Let 0/0 = 1. Then 0 * 1 = 0. It seems to work, but here there is a different problem. We could also say that 0/0 = 2 since 0 * 2 = 0; 0/0 = 3 since 0 * 3 = 0, etc. and now 0/0 can equal every number. The result of a division must be a unique answer, not all numbers.

When we try to divide a non-zero number by 0, no number works in the definition of division, so dividing a non-zero number by 0 is undefined. When we try to divide 0 by 0, every number works. Since there is no unique solution, 0/0 is also undefined. Therefore, division by zero is undefined.

Now the last part of your question.

What about 0 divided by 6?

0/6 = 0 if and only if 6 * 0 = 0. Well, 0 * 6 does equal zero. There is no other number that you can use as the quotient of 0/6 and have the corresponding multiplication equal zero, so 0/6 is indeed 0, and that operation is defined.

0 divided by any number other than zero is a defined division and equals 0.

Conclusion:

(any number)/0 is undefined

0/(any number other than zero) is defined and equals zero

Answer:

$13.50

Step-by-step explanation:

30 - (11.90 + 4.60) = 30 - 16.50 = 13.50

Step-by-step explanation:

Answer:

2(4z − 3 − 1) = 166 − 46

8z − 6 − 2 = 120

8z − 8 = 120

8z = 128

z = 16

pls give the brainliest

Step-by-step explanation:

Answer:

Step-by-step explanation:

you have to multiply 2(4z - 3 - 1 ). so 2 * 4z = 8z. so then you would do 2 * (-3) = -6. then you would do the same with -1. 2* (-1) = -2.

now you have to put it back in equation form. 8z - 6 - 2 = 166 - 46. now you have to combine like terms. -6-2 = -8. 166 - 46 = 120. and then put it back into equation form. 8z - 8 = 120. then you add 8 to 120. 120+8 = 128. now to find z all you have to do is divide 128/8 = 16

z = 16

Answer:

24

Step-by-step explanation:

6 ÷ 15 = 0.4

X to Y = 20 × 0.4 = 8

Y to Z = 25 × 0.4 = 10

Perimeter: a + b + c

6 + 8 + 10 = 24

Answer:

3m

Step-by-step explanation:

Product means multiplication, so you're multiplying 3 with m.

Step-by-step explanation:

simple interest formula is I = p × r × t / 100

$32 = p × 8 × 3 / 100

$32 = 24p / 100

32 × 100 = 24p

3200 / 24 = $133.33

Step-by-step explanation:

60% × ? = 9

? =  

9 ÷ (60 ÷ 100) =

       or

(100 × 9) ÷ 60 =

900 ÷ 60 =

15

How do we check the result?

If 60% × 15 = 9 =>

Divide 9 by 15...

... And see if we get as a result: 60%

Answer:

[tex]r=\frac{L}{2pi R}[/tex]

Diameter=2r

inches=12*ft

Step-by-step explanation:

You forgot to say how far the bike travels.

Given R rotations, L feet, and a wheel radius of r, then the relationship is

[tex]L=2\pi rR[/tex]

Solving this for r gives

[tex]r=\frac{L}{2pi R}[/tex]

Diameter=2r

inches=12*ft

Answer:

2 - [tex]b = 9\frac{1}{4}[/tex]

Step-by-step explanation:

Convert the mixed numbers into improper fractions.

2 • 2 + 1 = 5

4 • 11 + 3 = 47

[tex]\frac{5}{2} + b = \frac{47}{4}[/tex]

[tex]-\frac{5}{2} +\frac{5}{2} + b = \frac{47}{4} - \frac{5}{2}[/tex]

[tex]b = \frac{37}{4}[/tex]

[tex]b = 9\frac{1}{4}[/tex]

Step-by-step explanation:

Based on the altitude theorem of a right triangle, we have:

w + 4 = √(24*6)

w + 4 = √144

w + 4 = 12

w + 4 - 4 = 12 - 4

w = 8
