5 times a number subtracted from 12 is triple the number

1 answer:

6 0

5x-12=3x

Let's solve your equation step-by-step.
5x−12=3x
Step 1: Subtract 3x from both sides.
5x−12−3x=3x−3x
2x−12=0
Step 2: Add 12 to both sides.
2x−12+12=0+12
2x=12
Step 3: Divide both sides by 2.
2x/2=12/2

x=6

A polynominal function that describes an enclosure is v(x)=1500x_x2 where x is the length of the fence in feet what is the maxim

Maksim231197 [3]

Answer:

The answer is below

Step-by-step explanation:

A polynominal function that describes an enclosure is v(x)=1500x-x2 where x is the length of the fence in feet what is the maximum area of the enclosure

Solution:

The maximum area of the enclosure is gotten when the differential with respect to x of the enclosure function is equal to zero. That is:

V'(x) = 0

V(x) = x(1500 - x) = length * breadth.

This means the enclosure has a length of x and a width of 1500 - x

Given that:

v(x)=1500x-x². Hence:

V'(x) = 1500 -2x

V'(x) = 0

1500 -2x = 0

2x = 1500

x = 1500 / 2
