Answer:

-516

Step-by-step explanation:

Way #1

Step 1: Plug in x into the equation

-12(129) + 14(129) - 6(129)

-1548 + 1806 - 774

-516

Answer: -516

Way #2

Step 1: Or the other way is to simply the equation then plug x in.

-12(x) + 14(x) - 6(x)

-18x + 14x

-4x

Step 2: Then plug in x

-4(129)

-516

Answer: -516

Plug 129 for x
(-12 x 129)+(14 x 129)-(6 x 129)
Which would be -1548+1806-774
Which equals -516

What is the measure of ∠XYZ? Show your work to support your answer.

Shalnov [3]

3x + 20 = 5x - 16

3x - 5x = -16 - 20

-2x = -36

x = -36/-2

x = 18

The measure of angle xyz can also be said to be the measure of angle y.

So, y = (3•18 + 20)

y = 54 + 20

y = 74°

The measure of angle xyz = 74°.

A rectangular prism with a length of 7 centimeters, width of 5 centimeters, and height of 8 centimeters. A rectangular prism wit

Genrish500 [490]

Answer: The volume of the composite figure is $420\text{ cm}^3$ .

Step-by-step explanation:

We know that the volume of a rectanbgular prism is given by :-

Volume = length x width x height

Given, for prism 1 , we have

length of 7 centimeters, width of 5 centimeters, and height of 8 centimeters

Volume of prism 1= $(7)(5)(8)=280\text{ cm}^3$

Given, for prism 2 , we have

length of 10 centimeters, width of 7 centimeters, and height of 4 centimeters.

Volume of prism 2= $(10)(7)(4)=280\text{ cm}^3$

Now , the volume of the composite figure = Volume of prism 1+ Volume of prism 2

$=210\text{ cm}^3+210\text{ cm}^3=420\text{ cm}^3$

Hence, the volume of the composite figure is $420\text{ cm}^3$ .
