What is 2(x-4)+38=4x

Answers

Answer 1

Answer: Alright so first I got X=15.
To do this you will need to solve for X.
Step 1: Simplify both sides of the equation.
2(x−4)+38=4x
Simplify: 2x+30=4x
Step 2: Subtract 4x from both sides.
2x+30−4x=4x−4x−2x+30=0
Step 3: Subtract 30 from both sides.
−2x+30−30=0−30−2x=−30
Step 4: Divide both sides by -2.
−2x−2=−30−2x=15
And you get X=15! Hope I helped!

Answer 2

Answer: ∙•❁We are now going to solve your problem Step-By-Step, here we go!❁•

∙•❁Question:

2(x−4)+38=4x

∙•❁Simplify both sides of the equation:

2(x−4)+38=4x

∙•❁Let's simplify step-by-step:

2(x−4)+38=4x

(2)(x)+(2)(−4)+38=4x(Distribute)

2x+−8+38=4x

(2x)+(−8+38)=4x(Combine Like Terms)

2x+30=4x

∙•❁Subtract 4x from both sides:

2x+30−4x=4x−4x

−2x+30=0

∙•❁Subtract 30 from both sides:

−2x+30−30=0−30

−2x=−30

∙•❁Divide both sides by -2:

−2x/−2=−30/−2

∙•❁Your final answer is:

x=15

Find the minimum value of C=2x+y subject to the following constraints:
Please help!!!

Answers

Answer:

The minimum value of C is 20

Step-by-step explanation:

Sketch the constraints, that is sketch

2x + 3y = 24

with intercepts (0, 8 ) and (12, 0 )

4x + y = 38

with intercepts (0, 38 ) and (9.5, 0 )

The solutions lie above both lines

Solve 2x + 3y = 24 and 4x + y = 38 simultaneously to find point of intersection at (9, 2 )

The vertices of the feasible region are at

(0, 38), (9, 2) and (12, 0)

Evaluate the objective function for each of these vertices

C = 2(0) + 38 = 0 + 38 = 38

C = 2(9) + 2 = 18 + 2 = 20

C = 2(12) + 0 = 24 + 0 = 24

The minimum value of C is 20 when x = 9 and y = 2

Which shows one way to determine the factors of x3 + 4x2 + 5x + 20 by grouping?Which shows one way to determine the factors of x3 + 11x2 – 3x – 33 by grouping?

Answers

Answer:

1). (x² + 5) and (x + 4)

2). (x²- 3) and (x + 11)

Step-by-step explanation:

We have to determine the factors of the given expression (x³ + 4x² + 5x + 20) by grouping method.

x³ + 4x² + 5x + 20

= x²(x + 4) + 5(x + 4)

= (x² + 5)(x + 4)

Therefore, factors of the given expression are (x² + 5) and (x + 4).

Second expression is (x³ + 11x² - 3x - 33)

Now we will find the factors of this expression by grouping.

x³ + 11x² - 3x - 33

= x²(x + 11) - 3(x + 11)

= (x² - 3)(x + 11)

Therefore, the factors of the given expression are (x² - 3) and (x + 11).
