Answer:

Step-by-step explanation:

First you do whats in the parathesis.

2 + 2 = 4

Then you divide 6 and 12

6/12 = 0.5

Then you times what in the parathesis to both sides of the equation.

0.5(4)4

4 * 4 = 16

16 * 0.5 = 8

8 is the answer.

A rectangle has a perimeter of 2x^2+8x-10 the length of the rectangle is 3x-1. What is the width as an expression

4vir4ik [10]

Answer: The width is $x^{2}$ + 1x -4

Step-by-step explanation:

We know to find the perimeter we have to add the distance around the rectangle.The distance can also be sought as 2 times the length plus times the width.

So as a formula is like P = 2l + 2w where P is the perimeter.

We are given the perimeter so we can plot it into the formula and also plot in the length because it says the length is 3x -1

$2x^{2}$ +8x - 10 = 2(3x -1) + 2w Now we have to solve for w .Break it down

( $2x^{2}$ + 8x -10) = (6x -2 )+ 2w subtract 6x - 2 from both sides

( $2x^{2}$ + 8x -10) - (6x -2) = 2w

( $2x^{2}$ + 2x -8) = 2w now divide both sides by 2

$\frac{2x^{2} +2x-8 }{2} = w$ One the left side factor the numerator

$\frac{2(x^{2} +1x-4)}{2}$ = w Now multiply both sides by 2

w =( $x^{2}$ + 1x-4 )

The width is x^2 + 1x -4

Which equation best represents the data? y = –1.026x2 1016.402x – 162075 y = –1.036x2 1024.771x – 163710 y = 298.214x – 66317.66

yan [13]

Based on the items produced, and the profit yielded from those items, the best model to represent the data is y = -1.026x² + 1,016.402x - 162,075.

<h3>Which model shows the profit and items produced best?</h3><h3 />

You can find this out by testing the models using the items produced (independent or "x" value) to see if the model produces a close enough y value.

Assuming x is 100:

= -1.026x² + 1,016.402x - 162,075

= (-1.026 x 100²) + (1,016.402 x 100) - 162,075

= -$70,694.80

Assuming x is 400:

= -1.026x² + 1,016.402x - 162,075.

= (-1.026 x 400²) + (1,016.402 x 400) - 162,075.

= $80,325.80

These figures are very close to the actual y values given which makes this the best model.

The ___________ formula measures the length of a line segment or the distance between two points.

Morgarella [4.7K]

The distance formula measures the length of a line segment or the distance between two points.

The hypotenuse is one of the two sides that forms the right angle of a triangle.

The altitude of a triangle is a line segment that extends from the vertex and is perpendicular to the side opposite the vertex.
