2x^2+2x is it simplified

Mathematics
1 answer:
Tpy6a [65]3 years ago
4 0

Answer:

Yes it is simplified

Step-by-step explanation:

2x^2 is not a like term to 2x because 2x does not have an exponent. Therefore, you cannot add 2x to 2x^2. So it is as simplified as it can be at this point

What is the magnitude of the resultant vector a and b shown below?
denpristay [2]

Answer: SECOND OPTION.

Step-by-step explanation:

It is important to remember that, by definition, the "Resultant vector " is the vector obtained by adding two or more vectors.

 For this exercise you need to use the formula for calculate the magnitude of the resultant vector obtained by adding the vectors "a" and "b" shown in the picture attached:

c=\sqrt{a^2+b^2}

Where "c" is the magnitude of the resultant vector asked in the exercise.

You need to analyze the graph given in the exercise.

You can identify that:

a=4\\\\b=3

Then the next step, knowing which are "a" and "b", is to substitute values into the formula given at the beginning of this explanation, as following:

c=\sqrt{4^2+3^2}

Finally, evaluating, you get that "c" is:

c=\sqrt{16+9}\\\\c=5

The sum of two numbers is 50 and the difference is 14. What are the numbers?
sammy [17]

Answer: 18 and 32

Step-by-step explanation: The first thing you want to do is create a system of equations.

Let's use x to represent one number and y to represent the other.

So, we know that x+y=50 and x-y=14.

We can manipulate the second equation, making it x=y+14 by adding y to both sides. Then, now that we have an equivalent to x, we can plug it into the first equation to solve for y.

(y+14)+y=50

2y+14=50

2y=36

y=18

x+18=50

x=50-18

x=32

x=32, y=18
