Thus reduced form of the given expression, using identity [tex]a^{2} -b^{2} = (a+b) (a-b)[/tex] is [tex](x+6) (x-6)[/tex].

Given expression is

[tex]x^{2} -36[/tex]

[tex]x^{2} -6^2[/tex]

it is [tex](a+b) (a-b)[/tex]

In the same way, we can reduce [tex]x^{2} -6^2[/tex] .

Answer:

Step-by-step explanation:

The sum of angles in a triangle is 180°. In an isosceles triangle, the base angles are congruent.

For this, it is easiest to find the base angles first. If we let b represent the measure of one of them, the sum of angles is ...

  2b +42 = 180

  b +21 = 90 . . . . . . divide by 2

  b = 69 . . . . . . . subtract 21

The measure of the base angles is 69°.

__

Then we can find the value of x from its relation to the base angle measure:

  (2x +3)° = 69°

  2x = 66 . . . . . . . . . divide by °, subtract 3

  x = 33 . . . . . . . . divide by 2

The value of x is 33.

Answer:

x = 33

each base angle measures 69°

Answer:

Each text costs 5 cents ($0.05)

Step-by-step explanations:

To find the cost of one text, divide the $6.00 by 120.

You will come up with 0.05, meaning the correct answer is 5 cents

The cost of each text message is 0.05 dollar.

What is Unitary Method?

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given:

Cost of 120 text messages = $6

So, price to pay for 1 text message is

=6/120

=1/20

= 0.05 dollar

Hence, the cost of each text message is 0.05 dollar.

Answer:

C;  (5, 7)

Step-by-step explanation:

The quadratic function that has x-intercepts at x = 3, and x = -5 that

passes through the point (1, -12) is f(x) = x² + 2·x - 15.

The intercepts of the graph of the quadratic function are x = 3 and x = -5

The point through which graph passes is (1, -12)

Required:

The equation of the quadratic function.

Solution:

Given that the intercepts are x = 3, and x = -5, we have;

x = 3, and x = -5 are the zeros of the quadratic function, which gives;

Factors of the quadratic function are; (x - 3) and (x + 5)

From which we have;

(x - 3) × (x + 5) = x² + 2·x - 15 is a factor of the quadratic function

When x = 1, we have;

1² + 2 × 1 - 15 = -12

Therefore, the point (1, -12) is a point on the quadratic function x² + 2·x -

15 that has intercepts at x = 3, and x = -5

The equation of the quadratic function is therefore;

Answer: 132 square units

Step-by-step explanation:

Area of a trapezoid:

a = top base; b = bottom base; h = height

[tex]A=\frac{a+b}{2}+h[/tex]

Find the bases and the height:

b: 21 (given)

h: 8 (given)

a: find from the bottom

need to find the only not given value by subtracting the values we know. (this might be a little confusing but I think it'll be easier if you look at the original picture)

21 - 9 - 3 = 9

add the new number with the given length of the top base

9 + 3 = 12

Substitute the values into the equation:

[tex]A=\frac{a+b}{2}+h\\[/tex]

[tex]A=\frac{12+21}{2}+8[/tex]

(I used a calculator to find it out)

Area = 132 square units

Answer:

YES

Step-by-step explanation:

Why is the classmate correct?

The reason why the classmate is correct is that everything can turn 360 degrees. This means that a square, has to turn 360 degrees, and it does that by doing 90x4. This means that it has 90-degree angles, which turn 4 times. And that makes 360. That's how this is also correct. Because this classmate turned a figure 270 degrees clockwise, and also, 360-270=90, which means that turning that figure 90 degrees counter-clockwise will make it in that same position.

To check whether this is right or not, take an object, probably like a book. Then turn it 90 degrees to counter-clockwise, and note down the position, that the front of the book is now facing left, and the back of the book is now facing right. Then, turn it back to normal position, (back of the book facing you), then, turn it 3 times 90 degrees towards Clockwise, in that way, you can see, that the book turns in the same way it did when you did 90 degrees counter-clockwise!
