Answers

Answer 1
Answer:

Answer:

c:) 6(3 + 2x)

Step-by-step explanation:

The given expression is 18 + 12x. To simplify this expression, we can first look for any common factors that can be factored out. In this case, we can factor out 6, which gives:

18 + 12x = 6(3 + 2x)

So, the simplified expression 18 + 12x is 6(3 + 2x).

Answers

4(x + 2) = 3x + 4

Expand

4x + 8 = 3x + 4

Simplify

4x - 3x = 4 - 8

x = -4

Evaluate the answer

4(-4 + 2) = 3(-4) + 4

4(-2) = -12 + 4

-8 = -8 The answer is correct

The answer x = -4

Math. :)Question: 1.1W + 2.1 = 5.4
Answer: W = 2.2

Is the answer correct? How do you check the answer?

Thank you in advance!!

Answers

\sf~W+2.1=5.4

Subtract 2.1 to both sides:

\sf~W=3.3
This is one-step equation.
W+2.1=5.4 \n W+2.1-2.1=5.4-2.1 \n W=3.3 \n CHECK- \n 3.3+2.1=5.4

What are the four steps for solving a problem? Should any other factors be accounted for when solving a problem? Should any factors be accounted for when explaining how to solve a problem?

Answers

Analysis of the problem - working out what the problem is and setting down any testing that will happen to check that the solution works.

Design the solution - maybe there is more than one way to solve the problem, but the best way needs to be designed

Implementation of the design - produce the design: testing that the solution works should be included here

Evaluation - The solution is now used to solve the problem: Feedback is asked for to check that the solution does meet the original problem and solves it.

The function h(x)=x^2+3 and g(x)=x^2-6. if g(x)=h(x)+k, what is the value of k?

Answers

x^2-6=x^2+3+k\n k=-9
g(x) = x² - 6
h(x) = x² + 3

    g(x) = h(x) + k
  x² - 6 = (x² + 3) + k
  x² - 6 = x² + 3 + k
- x²       - x²
      -6 = 3 + k
     - 3  - 3
      -9 = k

The value of k is -9.
