First you bring the x to one side so u subtract 4x from 7x and you get the new equation as -9=3x+12 then you just solve and you get x is equal to -7
Answer:
3/8 = 9/24 ; 1/3 = 8/24 ; 3/8 > 1/3
Step-by-step explanation:
You have to multiply 8 and 3 to obtein the same number as denominatoe (24).
Once you have the same number you can use < = >

To answer this item, we take the differential of the equation and equate to zero.
C(x) = 0.8x² - 256x + 25939
Differentiation,
dC(x) = 1.6x - 256
dC(x) = 1.6x - 256 = 0
The value of x from the derived equation above is 160.
Thus, the number of machine to be made in order to minimize the cost should be 160.
The perimeter of the shape is 30 add all the sides
