A triangle has sides measuring 5 inches and 8 inches. If x represents the length in inches of the third side, which inequality gives the range of possible values for x?.

Answers

Answer 1

Answer: Let x = third side
Using the Triangle Inequality theorem which states that the sum of two sides of a triangle must be longer than the third side and the difference of the two sides is the lower limit of the third side, the answer to your question is that the third side must be between 3 and 13, or written using inequalities, 3 < third side (or x) < 13 is the range.

Answer 2

Answer: Hello,
As I said in last message, it exist an triangular inequality that is seen in Europe! An pupil of 16 years old should know it!!!
If a,b,c are the sides of a triangle it MUST exist these equality:
each side must be less then the sum of the others sides.

1)a<b+c
2)b<a+c
3)c<a+c

In the way:
5<8+x ==> x>-3 already done
8<x+5 ==>x>3
x<5+8==>x<13
thus 3<x<13

There seems to be a mistake in typing. You probably type the letter "i" as "1", so it is difficult to tell which numbers are complex numbers.

I will however explain what complex numbers look like, which will help you in determining which numbers are complex numbers, and the rest are real numbers.

Step-by-step explanation:

Complex numbers are numbers that include the square root of a negative number.

It is not possible to have a value for an expression with a square root of a negative number, then the letter j or i were introduced to help represent these kinds numbers.

√-1 = i or j (anyone is fine)

Knowing the square root of -1 is i, we can write the square root of any negative number with ease.

√(-6) = √(-1) × √6, right?

= i × √6

= i√6

And so on.

So, basically, the numbers that include the letter 'i', or √(-1) in them are the complex numbers. The rest are real numbers.

In our class, our class teacher gave us a project to complete in 15 days. The teacher assigned 4 consecutive projects, how many days will you have to complete the projects?

Answers

To do this we will just DIVIDE. Lets Divide:-

15 ÷ 4 = 3.75

Check our work:-

3.75 × 4 =15

So, to finish 1 project you have 3.75 days.

how do I figure out the weight loss of tina? she lost 3 pounds on the first week of her diet. she gained a pound on the second week, and then lost 2 pounds a week during every week afterwards. she has been dieting for a total of 13 weeks. how many pounds has tina lost in all?

Answers

1st week - Lost 3 pounds = +3
2nd week - Gained 1 pound = -1
3+13 = + 22

So 22+3 = 25 25-1 = 24

So Tina lost 24 pounds in 13 weeks.
