What is the circmference and ared of a circiewith a radius of 4 meters? round you answer to the nearest tenth

Tasya [4]

Answer:

$\boxed{x=5}$

Step-by-step explanation:

Division property of equality- is dividing both sides of an equation by the same non-zero number it does not change the equation.

First you had to divide by six from both sides of an equation form.

$\frac{6x}{6}= \frac{30}{6}$

$30/6=5$

$30/5=6$

$5*6=30$

$6*5=30$

$x=5$

$5=x$

Final answer: $\boxed{x=5}$

Hope this helps!

And thank you for posting your question at here on brainly, and have a great day.

Dan factored x^2+121 into (x+1-11)

babunello [35]

Answer:

Your question is a little unclear. If you are just trying to factor x² + 121, it's prime. (can't be factored using real numbers).

Step-by-step explanation:

The difference of two squares is a special form. a² - b² = (a+b)(a-b).

But, the sum of two squares is prime. a²+ b² cannot be factored.

<h3>Answer: 5.5 which is choice B</h3>

Have a look at the diagram I posted below. I marked on your image to add in another angle. This angle is also 20 degrees because of congruent alternate interior angles (horizontal lines are parallel). This angle I add in is the reference angle of the triangle

opposite the reference angle is the vertical side x

adjacent to the reference angle is the horizontal side 15

We'll use the tangent rule. Make sure your calculator is in degree mode.

tan(angle) = opposite/adjacent

tan(20) = x/15

15*tan(20) = x <<-- multiply both sides by 15

x = 15*tan(20)

x = 5.45955 <<--- use calculator; this is approximate

x = 5.5 <<--- round to one decimal place
