Answer:

\huge \boxed{g( - 4) = 14}

Step-by-step explanation:

g(x) = 6 - 2x

To find g(-4) , substitute the value of x that's - 4 into g(x). That is for every x in g(x) , replace it with - 4

We have

g( - 4) = 6 - 2( - 4) \\  = 6 + 8 \\  = 14  \:  \:  \:  \:  \:

We have the final answer as

<h3>g(-4) = 14</h3>

Hope this helps you

A brick is in the shape of a rectangular prism with a length of 8 inches, a width of 3.5 inches, and a height of 2 inches. The b
givi [52]

The mass of brick is 2478 gram

<em><u>Solution:</u></em>

A brick is in the shape of a rectangular prism with a length of 8 inches, a width of 3.5 inches, and a height of 2 inches

Length = 8 inches

Width = 3.5 inches

Height = 2 inches

<em><u>The volume of rectangular prism is given as:</u></em>

volume = length \times width \times height

volume = 8 \times 3.5 \times 2\\\\volume = 56

Thus volume of brick is 56 cubic inches

<em><u>Convert inches to centimeter</u></em>

1 inch = 2.54 centimeter

Therefore,

56 cubic inches = 56 x 2.54 x 2.54 x 2.54 cubic centimeter

56 cubic inches = 917.676 cubic centimeter

Thus, we get,

volume = 917.676 cubic centimeter

The brick has a density of  2.7 grams per cubic centimeter

Density = 2.7 grams

<em><u>The mass of brick is given by formula:</u></em>

mass = density \times volume

<em><u>Substituting the values we get,</u></em>

mass = 2.7 \times 917.676\\\\mass = 2477.724 \approx 2478

Thus mass of brick is 2478 gram

The volume of a cube is 8000 cubic feet, what is the area of one of its faces?
eimsori [14]

Since a cube is l x w x h, find the length of one side first:

∛8,000 = 20

The length of one side is 20 feet. This can represented as "s".

To find the area of one of the faces, use s²:

20²   or   20 x 20 = 400

The area of one face is 400 ft²!
