what expression represents an equilateral triangle if all of the sides measure (6x - 6.3) as a sum?

a) 2x + 2x + 2x - 2.1
b) x - 2.1 + x - 2.1 + x - 2.1
c) 2x - 2.1 + 2x - 2.1 + 2x - 2.1
d) 2x - 2.1 + 2x - 2.1 + 2x - 2.1 + 2x - 2.1

Answer:

Paper Lanterns: 4

Bags of Balloons: 12

Garlands: 11

Banners: 4

Step-by-step explanation:

Cost of lanterns is $6.50

Mrs. Murphy bought 4 lanterns

Multiply the cost of one lantern ($6.50) by the number of lanterns bought (4)

6.50 multiplied by 4 equals 26

Cost of banners is $5.25

Mrs. Murphy bought 4 banners

Multiply the cost of one banner ($5.25) by the number of banners bought (4)

5.25 multiplied by 4 equals 21

Mrs. Murphy bought 3 times as many balloons as she did lanterns

So, you multiply the number of lanterns bought (4) by 3

This gives you 12

You then multiply the cost of each balloon ($5.00) by the number of balloons bought (12)

5.00 multiplied by 12 equals 60

Mrs. Murphy bought 7 more garlands as she did lanterns

So, you add 7 to the number of lanterns bought (4)

7 plus 4 equals 11

To find the cost of the total garlands bought

You multiply the cost of each garland ($3.50) by the number of garlands bought (11)

3.50 multiplied by 11 equals 38.5

Now you can add up the costs of all the items

26+21+60+38.5=145.50

145.50 was the total amount she spent so you know it is the correct answer.

3rd Option

Step-by-step explanation:

Volume = (2x-5)*(2x+5)*3x

Volume = (4x^2 + 10x - 10x -25)*3x

Volume = 12x^3 +30x^2 -30x^2 - 75x

Volume = 12x^3 - 75x

The expressions represent the volume of the prism is

V = 12x^2 - 75x

The formula for calculating the volume of rectangular prism is expressed as:

V = lwh

l is the length

w is the width

h is the height

Given the following

l = 2x + 5

w = 2x - 5

h = 3x

V =  3x(2x+5)(2x-5)

V = 3x(4x^2 - 25)

V = 12x^2 - 75x

Hence the expressions represent the volume of the prism is

V = 12x^2 - 75x

Answer:

5. D  6. B   7. C

Step-by-step explanation:

All side lengths of a rhombus are the same therefore the length of WZ must be 4cm.

The sum of all the angles in a rhombus add up to 360 degrees, since we already have 2 100 degrees( opposite interior angles are the same) then the rest must be 80 degrees angles.

Answer:

14.4 inches

Step-by-step explanation:

Use the Pythagorean theorem: [tex]a^{2} + b^{2}[/tex]

So, this will be: [tex]8^{2} + 12^{2} = c^{2}[/tex]

By simplifying we get:

c = [tex]\sqrt{208}[/tex]

The missing side is: 14.4 (rounded to the tenth)

Answer:

[tex] \displaystyle 4 \sqrt{13}in [/tex]

Step-by-step explanation:

we are given a right angle triangle and we want to figure out the missing hypotenuse in order to do so we can consider using Pythagoras theorem given by

[tex] \displaystyle {a}^{2} + {b}^{2} = {c}^{2} [/tex]

[tex] \displaystyle \implies{c}^{} = \sqrt{ {a }^{2} + {b}^{2} } [/tex]

let a and b be 8 and 12 respectively thus

substitute:

[tex] \displaystyle {c}^{} = \sqrt{ {8 }^{2} + {12}^{2} } [/tex]

simplify squares:

[tex] \displaystyle {c}^{} = \sqrt{ 64 + 14 4} [/tex]

simplify addition:

[tex] \displaystyle {c}^{} = \sqrt{208} [/tex]

by simplifying the redical expression we obtain:

[tex] \displaystyle {c}^{} = 4 \sqrt{13} [/tex]
