Answer:
Step-by-step explanation:
First get the answer to -3n - 4 = 2
-3n - 4 + 4 = 2 + 4
-3n = 6
n = 6/-3
n = -2
That answer is the only one that is permitted. It is the only one that completely satisfies the equation.
Now when you do the inequality, look what happens.
-3n - 4 < 2 Add 4 to both sides.
-3n-4+ 4 < 2+4
-3n < 6 Now there are a bunch of ways (2) to solve this.
No matter which way you do it, the arrow will change.
-3n/-3 > 6/-3
n > - 2
That means that any number that is greater than - 2 will satisfy the inequality.
So n = 0 will work. Even n = - 1 will work. Anything bigger than -2 will work. The equation does not provide that kind of latitude.
Answer:

Step-by-step explanation:
To solve the problem shown above you must apply the following proccedure:
1. Let's call:
x: a number.
f: the factor.
2. Then, you have:
√fx=3√x
3. You must clear the factor "f" to calculate its value, as below:
√fx=3√x
(√fx)²=(3√x)²
fx=9x
f=9x/x
4. Then, the factor is:
f=9
5. Therefore, b<span>y what factor must you multiply a number in order to triple its square root?

The answer is: 9
Answer: <u>38.4845100065m²</u>
<em>when rounded to the nearest tenth: </em><u>38.5m²</u>
<em>when rounded to the nearest hundredth: </em><u>38.48m²</u>
<em>when rounded to the nearest thousandth: </em><u>38.485m²</u>
Step-by-step explanation:
the formula for finding the area of a circle is
, where A = area and r = the radius of the circle.
since you're only given the circumference, we need to calculate the radius of the circle before we can find the area.
- to find the radius of a circle, you can either <u>divide the measure of the diameter by 2</u> <em>OR</em> <u>use the formula</u>
where r = radius and C = circumference. - because there is no given diameter measurement in your question, <u>the best way to find the radius is to use the formula</u>
.
first, plug the given values into the equation.
since
is the given circumference, plug in
for
.
⇒ 
- the equation becomes
, aka <em>radius equals seven times pi divided by two times pi</em>.
now divide
.
now we know that the radius of the circle is 3.5 :) since we have this information, we can now solve for the area of the circle using the formula
.
first, plug in
for
.
⇒ 
now multiply
, aka <em>pi times three and five tenths squared</em>.
<em>(if needed, you can round this result to the nearest tenth, hundredth, etc.)</em>
