I believe it would be something related to the corresponding numbers.
they are saying x = 3 so you would use the middle equation
so -4x becomes -4(3)
-4 * 3 =-12
For twice a number we can use the variable x
For four times a number we can use the variable c
4c - 2x + 15
I believe this is correct although I'm not 100% sure
Answer:
Step-by-step explanation:
Volume of the shipping container = Lengt * Breadth * Height
Given
Length = 4x² + 3x
Breadth = x² – 8
Height = 6x +15
Volume of the container = ( 4x² + 3x)( x² - 8)(6x+15)
( 4x² + 3x)( x² - 8) = 4x⁴-32x²+3x³-24x
( 4x² + 3x)( x² - 8) = 4x⁴+3x³-32x²-24x
(4x⁴+3x³-32x²-24x)(6x+15) = 24x⁵+60x⁴+18x⁴+45x³-192x³-480x²-144x²-360x
Collect like terms
( 4x² + 3x)( x² - 8)(6x+15) = 24x⁵+78x⁴-147x³-624x²-360x
Hence the standard form polynomial representing the volume of this shipping container is expressed as V = 24x⁵+78x⁴-147x³-624x²-360x
We know, 4/2 = 2
& 4/4 = 1
So, 4/2 > 4/4
In short, Your Final Answer would be Option C
Hope this helps!
