Answer:
( f + g )( x ) = 8x - 3
Step-by-step explanation:
What this is saying is to add the two functions together.
( 5x+1 ) + ( 3x - 4 )
( f + g )( x ) = 8x - 3 is the simplified version.
The side length of the square base is 18 inches and the height of the pyramid is 9 inches.
Step-by-step explanation:
Step 1:
The volume of a square pyramid is calculated by multiplying the square of the base edge with the height of the pyramid and
.
The volume of a square pyramid, 
Step 2:
From the given diagram, the base edge is the length of the four base edges which is x inches in this pyramid. a = x inches.
The height of the pyramid is from the base to the top, h =
inches .
The volume of a square pyramid, 
Substituting the known values, we get

![x^{3} = 6(972) = 5,832. x = \sqrt[3]{5,832} = 18.](https://tex.z-dn.net/?f=x%5E%7B3%7D%20%3D%206%28972%29%20%3D%205%2C832.%20x%20%3D%20%5Csqrt%5B3%5D%7B5%2C832%7D%20%3D%2018.)
So x is 18 inches long.
The side length
inches.
The height of the pyramid
inches.
(5(2x))^3
Use the property of exponents:
(5^3)*(2x)^3
Simplify the exponents:
125*8*x^3
Simplify the numbers and multiply the integers:
1000*x^3
Hope this helps :)
Hi there!
Answer:
<u><em>=4x</em></u>
Step-by-step explanation:
Distributive property: ⇒ a(b+c)=ab+ac
You had to add similar elements.
9x-5x=4x
5x+4x=9x
9x-4x=5x
final answer: =4x
Hope this helps!

Have a great day!
There is 3600 seconds per hour.
Multiply the speed per second by 3600 to get the speed in miles per hour then convert to kilometer/hour.
4.9 * 3600 = 17,640 miles per hour
17,640 x 1.6 = 28,224 kilometers per hour
