The area of a square = side times side.

In short, A = s times s or s^2

81 = s^2

Taking the square root of both sides, we get s = 9cm.

To find the diagonal, we use the Pathygorean Theorem.
Let d = the diagonal representing the hypotenuse of the right triangle formed by two sides of the square and the diagonal.

(side)^2 + (side)^2 = (diagonal)^2

9^2 + 9^2 = d^2

81 + 81 = d^2

162 = d^2

Taking the square root of both sides, we get d = sqrt{162}.

The length of the diagonal is the square root of 162
written as sqrt{162}.

m = (-6-9)/(-12-(-12)

m = -15/0

Let m = slope

Since we cannot divide by zero, then the answer is UNDEFINED SLOPE.

This means, the slope DOES NOT EXIST for the given two points.

The line that connects the two given points is surely a vertical line for the slope of vertical lines does not exist. The line that connects these two points is the line x = -12, which is a vertical line.

n + n + 1 = 27

2n + 1 = 27

2n = 27 - 1

2n = 26

n = 26/2

n = 13

The numbers are 13 and 14.

A = (h/2)(B + b)
Let B = 15
Let b = 7

As you can see, more information is needed. I need to know the value of A in order to find h (our height).
You did not provide the area of the isoceles trapazoid. So, it is impossible to find the height without knowing the value of A.

Understand?

A = pi(r^2)

4 1/2 can be written as an improper fraction 9/2.

So, let r = 9/2

A = pi(9/2)^2

Let pi = 3.14

A = 3.14(9/2)^2

A = 3.14(81/4)

A = 3.14(20.25)

A = 63.585in^2

We now round to the nearest hundredths AKA second decimal place.

A = 63.59in^2

Use the following two formulas:
For area use: A = Length times width
For perimeter use: P = 2(length) + 2(width)

L = 12, W = 4

A = 12 times 4

A = 48in^2

The area is 48 squared inches.

==============================
P = 2(12) + 2(4)

P = 24 + 8

P = 32 inches

The perimeter is 32 inches.

The figure given is a rectangle not a square.

The other question:


8x – (6x + 7) = -1

8x - 6x - 7 = -1

2x - 7 = -1

2x = -1 + 7

2x = 6

x = 6/2

x = 3

To find domain for g(x), set denominator to zero and solve for x.

10 - 7x = 0

-7x = -10

x = -10/-7

x = 10/7

DOMAIN = ALL REAL NUMBERS EXCEPT THAT X CANNOT EQUAL 10/7.

WHY CAN'T X = 10/7 HERE?

If x is replaced by the fraction 10/7, division by zero is made.

Since division by zero does not exist, x CANNOT BE 10/7.

Let D = 4 in the equation and solve for T.

T = 0.07D^(3/2)

T = 0.07(4)^(3/2)

T = 0.07(sqrt4{4})^3

T = 0.07 times (2)^3

T = 0.07 times 8

T = 0.56

We now convert 0.56 to time in hours.

0.56 times 60 minutes in one hour = 33.6 minutes.

Now, multiply 0.6 (which is the decimal part of 33.6) times 60 = 36 seconds.

Final answer for T = 0.0 hours, 33 minutes and 36 seconds.

Greatest Common Factor: The highest number that divides exactly into two or more numbers. It is the "greatest" thing for simplifying fractions!
What is the BIGGEST number that evenly divides 54 and 96?

How about 6?

54/6 = 9

96/6 = 16

Yes, that's correct.

The least common multiple (LCM) of two numbers is the smallest number (not including zero) that is a multiple of both.

Multiples of 3O: 30, 60, 90, 120, 150, 180, 210

Multiples of 42: 42, 84, 126, 168, 210

On the list provided, what number is found in both?

The number 210 is found in both.

Then 210 is the LCM.

x^6 - 9y^2 factors out to be (x^3 - 3y)(x^3 + 3y).

If you multiply (x^3 - 3y) by (x^3 + 3y), it will take you back to the given problem. This is how we know when the answer is correct in terms of factoring.
Factoring is the opposite of multiplication.

Let her son be s years old. She is s + 33 years old.
In four years time this becomes s + 4 and s + 37.
so, 4(s + 4) = s + 37
=> 4s + 16 = s + 37
=> 3s = 21
so, s = 7
i.e. their ages are 7 and 40.

Any letter by itself is divided by 1.
In other words, a is really a/1. So, a/1 = a because ANYTHING divided by 1 equal ANYTHING. Understand?

This does not change your equation.

The equation 5 = a/1 + 4/3 is EXACTLY the same as 5 = a + 4/3.

Multiply every term on both sides of the equation by 3. This will remove the fraction on the right side.


5 times 3 = a/1 times 3 + (4/3) times 3

15 = 3a + 4

15 - 4 = 3a

11 = 3a

We now divide 11 by 3 to find a.

11/3 = a
The correct answer is not 11 but the improper fraction 11/3.
So, a = 11/3 is the answer.

We have 17/35 = -x

Remember that any letter standing alone, for lack of a better word, has a factor of 1 next to it. In other words and for your question, -x is really -1 times x. Did you know that?

We multiply both sides of the equation by 35 as step one.

35 times (17/35) = -x times 35

17 = -35x

To find x, we now simply divide 17 by -35 (our step two).

17/-35 = x

-17/35 = x

Let x = first integer

Let x + 1 = second integer

x + x + 1 = 624

2x + 1 = 624

2x = 624 - 1

2x = 623

x = 623/2

x = 311.5

The first number is 311.5 and the other is 312.5 and that's it.

f(x) = sqrt {x-1}
The domain is all values that x can take on.
I'll set the insides greater-than-or-equal-to zero, and solve. The result will be my domain.

x - 1 ≥ 0

Adding 1 to both sides of the inequality, I get:
x ≥ 1

The domain is "all x ≥ 1."

Let x = (x + h)

f(x + h) = (x + h)^2 + 2(x + h) + 1

f(x + h) = x^2 + 2xh + h^2 + 2x + 2h + 1

All you had to do is replace every x in the function with the value (x + h) and simplify.

Use A = pi(r^2)

The diameter is 16 inches which means that the radius must be 6 inches.

radius = diameter divided by 2.

We now plug and chug and leave our answer in terms of pi. This means we do NOT use 3.14 for pi.

A = pi(6)^2

A = 36pi

Done!

If the answer is 6, then when we replace x with 6, the answer should be 0, right?

x^2 + x - 42 = 0...This is your quadratic equation.

Let x = 6

(6)^2 + 6 - 42 = 0

36 + 6 - 42 = 0

42 - 42 = 0

0 = 0...IT CHECKS!!!

Yes, the answer is x = 6.

It is not possible to have a right triangle with the given sides where 19 represents the hypotenuse.
The reason is that in this case the sum of the squares of sides 7 and 13 DOES NOT equal the hypotenuse 19 squared.

LOOK:

7^2 + 13^2 = 19^2

49 + 169 = 361

218 DOES NOT EQUAL 361.
