150 is what percent of 30

2 answers:

8 0

For this, what you need to do is 150/30 x 100. When you do this, you get 500%. Another way to look at this is that you know that in this case, 30 is 100%. 150 is 5 x 30 so it must be 500%

Factor x3 + 2x2 + x completely. a. (x+1)^2 b. x(x+1)^2 c. x(x+1)^2

enot [183]

Option B

ANSWER:

The factors of $x^{3}+2 x^{2}+x$ is $x(x+1)^{2}$

SOLUTION:

Given, cubic expression is $x^{3}+2 x^{2}+x$

Now, we have to find the factors of above equation.

To factorize the given equation, follow the below steps:

$\mathrm{x}^{3}+2 \mathrm{x}^{2}+\mathrm{x}$

Since x is common in every term of expression, we can take it as common

$x\left(x^{2}+2 x+1\right)$

“2x” can be rewritten as “x + x”, the above equation becomes,

$x\left(x^{2}+x+x+1\right)$

Taking the common terms out of bracket. we get

x(x (x + 1) + 1 (x + 1))

Taking (x + 1) as common., we get

x ((x + 1)(x + 1))

$x(x+1)^{2}$

Hence, the second option b is correct.

What is a simplest way to find out x

konstantin123 [22]

Answer:

You should start with a simple equation. And remember- practice makes perfect.

The basic algebraic equation involves simple addition or subtraction with one unknown quantity, such as 2 + x = 7.

1. Subtract 2 from both sides: 2 - 2 + x = 7 - 2.

2. Simplify the equation by doing the math: 2-2+x=7-2=0+x=5, or x = 5.

3. Check your work by substituting the answer, 5, into the equation for x.

The correct answer is x=5.
