dont say C just becuase its chosen, i didnt mean to

Answers

Answer:

Step-by-step explanation:

(4x^2-x+6)-(x^2+3)

First, you can change the second polynomial to make it an addition problem.

(4x^2-x+6)+(-x^2-3)

Then you add them together so 4x^2-x^2=3x^2

-x has nothing to subtract or add so we bring it down

and 6-3=3 making the answer

3x^2-x+3

A. 0, 8, 16, 24, ...
B. 22, 14, 6, -2, ...
C. -22, -30, -38, -46,...
D. -14, -6, 2, 10, ...

Answers

Answer:

D. -14, -6, 2, 10, ...

Step-by-step explanation:

Plug in the values for x.

8(1) - 22 = x

8 - 22 = x

-14 = x

8(2) - 22 = x

16 - 22 = x

-6 = x

8(3) - 22 = x

24 - 22 = x

2 = x

8(4) - 22 = x

32 - 22 = x

10 = x

Answers

Step-by-step explanation:

Mid point formula ,

x = (x1+x2)/2 , y = (y1+y2)/2

x = 1 , y = 4

therefore ,midpoint is (x, y)= (1,4)

Look at the pentagonal numbers. Use finite differences to determine which function represents the pattern.

f(x) = 1.5x - 0.5x

f(x) = 1.5x^2 + 1.5x

f(x) = 1.5x^2 - 0.5v

f(x) = 0.5x^2 + 0.5x

Answers

Answer:

f(x) = 1.5x - 0.5x

Step-by-step explanation:

The function of the pattern represented by the pentagonal numbers is the sum of three triangular numbers.

The triangular number general formula

x (x + 1) / 2

For example,

The sequence

1, 3, 6, 10

* * *

* * * * * *

* , * *, * * *, * * * *

_____________________________

The pentagonal numbers

The sequence:

1, 5, 12, 22, 35

As shown in the picture can be divided into three triangles

Triangle 2

x (x + 1) / 2

Triangle 1 and 3 (they are triangles one unit smaller than 2)

n (n + 1) / 2

n= x-1

Replacing n

(x-1) ((x-1) + 1) / 2

(x-1) (x) / 2

(x-1) x / 2

______________

Function represents the pattern

Triangle 2 + (Triangle 1 + Triangle 3)

Triangle 1 = Triangle 3

So then,

Triangle 2 + 2* Triangle 1

x (x +1) /2 + 2* (x -1) x/2

Rearranging

0.5 x (x +1) + x(x -1)

0.5x^2 + 0.5x + x^2 -x

(0.5 x^2 + x^2) + (0.5x -x )

1.5 x^2 - 0.5 x

Solve the equation for x.

Answers

Answer:

Step-by-step explanation:

x/13=10

We have to get rid of the 13. (the denominator)

How?

By multiplying 2 sides by 13

Remember the Rules of Maths:

1. Whatever you do to one side, you must do to the other.

2. Use the opposite operation.

So, we used Rule 2 to get rid of the 13.

Now:

x=10*13

(On the left side, the 13s cancel)

x=130

It is always a great idea to double-check

Does 130 divided by 13 equal 10?

Of course it does!

Have a great day!!

I hope everything is clear!

1 Serek is showing how to model the area

formula of a triangle

1) Original triangle

2) Create a congruent triangle.

Rotate it then join it to the original

triangle, forming a parallelogram.

3) Decompose the parallelogram

into a right triangle and a trapezoid.

4) Rearrange the triangle and

trapezoid to form a rectangle.

Which of these steps will identify the area

of the original triangle?

A Find the total area of the trapezoid

B Find half the area of the rectangle

C Find half the area of the trapezoid

D Find the area of the shaded triangle

5.80

Answers

Answer:

Find half the area of the rectangle

Step-by-step explanation:

Given

See attachment for the Serek's steps

Required

Which can be used to determine the area of the original triangle

To do this, we simply analyze each step.

At step 2, where he joined two congruent triangles to form a parallelogram.

Half the area of the parallelogram will give the area of the original triangle (since both triangles are equal)

At step 3, where he decomposed the parallelogram to a trapezoid and a right triangle.

Half the sum of the areas of the resulting shapes (trapezoid and right triangle) will equal to the area of the original triangle but half the area of each shape will not amount to the area of the original triangle

At step 4, where the right triangle and the trapezoid are merged to form a rectangle.

The area of the rectangle will equal to the area of the parallelogram in step (2).

So, half the area of the rectangle will equal to the area of the triangle.

Hence, (b) is correct

There is a sales tax of $6 on an item that costs $64 before tax. The sales tax on a second item is 8.25. How much does the second item cost before tax?

Answers

For the Item that costs $64 before tax the sales tax is $6
Hence for the item that costs $1 before tax the sales tax is $(6/64), by the rule of proportions or unitary method
Hence for the item that costs $100 before tax the sales tax is $[100*(6/64)], by the rule of proportions
which is = $75/8 or $9.45

Therefore, the item having a Sales tax of $9.45 or $75/8 costs $100 before tax
thus the item having a Sales tax of $1 costs $[(100*8)/75] before tax, by the rule of proportions or unitary method
thus the item having a Sales tax of $8.25 costs $[(100*8*8.25)/75] before tax, by the rule of proportions
which is = $88

The length of a rectangle is 5 units longer than its width, w. Select the expression that represents the perimeter of the rectangle.

Answers

Answer: The expression that represents the perimeter of the rectangle is given as

Perimeter= 4x +10

Step-by-step explanation:

Perimeter= 2l+2w =2( l+w)

Let the width be =x

And Length=x+5

So that the Perimeter =2l+2w becomes

Perimeter =2x +2(x+5)

Perimeter =2x+2x+10

Perimeter= 4x +10

How far did the player run?
Round your answer to the nearest meter.

Answers

So this is going to create a right triangle which you and his run will create the hypotenuse, so we will use
a^2+b^2= c^2
a and b are given... 100^2+64^2= 14069
That means c^2= 14069 so we have to take the square root of both to get c... which gives us 118.7265766373 which to the nearest meter is 119.
