Kelly goes to the store and buys 9 boxes of cookies. The cost of each box is represented with the letter c. Which expression could you use to show how much money Kelly spent?

Answers

Answer 1

Answer:

9c because you don't know how much money Kelly actually spent so instead of doing 9 x the price of each box, you replace it with c, so it's 9c

the perimeter of a rectangle garden is 43.8 ft it's length is 12.4 ft what is the width​

Answers

Answer:

9.5 ft

Step-by-step explanation:

Since it is a rectangle. The lengths are the same and the widths are the same.

12.4 + 12.4 = 24.8

43.8 - 24.8 = 19

19/2 = 9.5

The length of the rectangle shown below is represented by the expression (x - 2)2. The width is represented by the expression (3x - 5). What is the area of the rectangle?

Answers

Answer:

(6x² - 22x + 20) square units

Step-by-step explanation:

The area of a rectangle is calculated as:

Length × Width

From the question

Length = (x - 2)2 = 2x - 4

Widths = 3x - 5

The area of the rectangle =

(2x - 4 ) × (3x - 5)

2x(3x - 5) -4(3x - 5)

6x² - 10x - 12x + 20

6x² - 22x + 20

The area of the rectangle =

(6x² - 22x + 20) square units

the answer to the equation is 7.6

Write an equation in slope-intercept form of the line going through the points (-1,6)
and (5, 0).

Answers

Answer:

Equation in slope-intercept form : y = -1x + 5

Step-by-step explanation:

Given points are:

(-1, 6) and (5,0)

We will first find the slope.

[tex]m = \frac{y_2-y_1}{x_2-x_1}\\\\m = \frac{0-6}{5-(-1)}\\\\m = \frac{-6}{6}\\m = -1[/tex]

The general equation for slope intercept form is;

y = mx + b

Now we will find the value of b by putting one of the points in the general equation

Putting (5,0)

0 = -1(5) + b

0 = -5 + b

b = 5

The equation in slope intercept form is;

y = -1x + 5

Hence,

Equation in slope-intercept form : y = -1x + 5

To check which set does not make a right triangle, let us check if each set is a Pythagorean triplet:

A) 3, 4, 5
(3)^2+(4)^2=(5)^2
= 9+16=25
= 25=25

B) 5, 12, 13
(5)^2+(12)^2=(13)^2
= 25+144=169
= 169=169

C) 9, 40, 41
(9)^2+(40)^2=(41)^2
= 81+1600=1681
= 1681=1681

D) 7, 8, 15
(7)^2+(8)^2=(15)^2
= 49+64=225
= 113≠225

Thus, the set of side measures 7, 8, 15 does not form a Pythagorean Triplet, and thus not a right triangle.

Answer:

hope this displays, sorry if it doesn't

Step-by-step explanation:

If we take (1,2) and (2,4) then the slope will be 2. and is we change it to (3,5) and (8,8) then slope will be 3/5.

What is slope?

The slope is the vertical distance which is calculated by ratio of difference between y coordinates and x coordinates.

How to find slope?

The formula of slope is (y2-y1)/(x2-x1).

Points A and B are (1,2) and (2,4) then slope=4-2/2-1=2

Length of line will be [tex]\sqrt{(4-2)^{2} +(2-1)^{2} }[/tex]

=[tex]\sqrt{4+1}[/tex]

=[tex]\sqrt{5} units[/tex]

Change the points to (3,5) and (8,8)  slope becomes=8-5/8-3=3/5

length of line will be [tex]\sqrt{(8-5)^{2} +(8-3)^{2} }[/tex]

=[tex]\sqrt{9+25}[/tex]

=[tex]\sqrt{34}[/tex] units.

let the ratio be 2:9

If we select this and divide using 2:9 then it will become 2:9.
