Can triangles be made with sides length of 15,10,4

1 answer:

7 0

Answer is No.

The reason why is that

One side of the triangle has to be less than the sum of the other two sides and greater than the magnitude of their difference.

Rule 1: (side1 + side2) > side3

Rule 2: Side3 < |side1 - side2|

Lets check the fact by adding / subtracting two sides and comparing with the third one..

Case1: 7+ 8 = 15 = length of third side. Rule1 fails

Case2:

8+15 > 7 Rule1 sucess

15–8 = 7 = length of third side. Rule 2 fails.

Case3:

7+15>8 Rule1 success

15–7=8 = length of third side. Rule 2 fails.

So, considering the rules and checking the facts..

it is impossible to create a triangle with above 3 sides.

Elza [17]

Answer:

Step-by-step explanation:

Given: $\frac{1}{2} ? \frac{1}{3}$

Want: Which fraction is larger?

To identify the size of a fraction, converting it into a fraction is easier

$\frac{1}{2}$ = 0.5

$\frac{1}{3}$ = 0.33

where 0.5 is greater than 0.33

Choices:

< is less than symbol

> is greater than symbol

= is equal to

$\frac{1}{2} > \frac{1}{3}$

What is 25% of 400 5% of 20

stiks02 [169]

Hello there!

What is 25% of 400?

$\frac{25*400}{100}$

= $\frac{10,000}{100}$

= 100

Thus,

25% of 400 is 100

What is 5% of 20?

Well, we just need to follow the previous steps.

$\frac{5*20}{100}$

= $\frac{100}{100} = 1$

Thus,

5% of 20 is 1

I hope this answer helps. Let me know if you have additional questions about the answer. As always, it is my pleasure helping student like you.

Which student factored the expression x3 - 7x - x2 + 7 correctly based on their answer below?

Verizon [17]

We can check the end terms first

for
(a+b)(c+d), the first term of the expanded is ac and the last term is bd

so
the expanded is x^3 and last is +7

jane will have a lst term of -7 so no
mariah wil have last term of -7 as well, so no
only rojer and nethan have last tem of +7

so we can do the rest of it by doing the OL part of FOIL

do either roger or nethan
let's do nethan

F=x^3
O=-7x
I=-x^2
L=7
yep

it is nethan
