What are the possible side lengths of a triangle

Mathematics

NONE of those lengths will form a triangle.
Basically, the longest side of a triangle must be less than the sum of the other 2 sides.  In this case NONE of those choices will form a triangle.

Hey!
So to find this you have to add the 2 smaller lengths and see if they are larger than the largest length. 
3 + 5 is 8 and that is not greater than 9 so A is wrong
4 + 8 is 12 and it is larger than 10, so maybe...
6 + 9 is 15 and that is not larger than 17 so that is out
8+10 is 18 and that is equal to but not larger than 18 so that is out
Your answer is B!
Hope this helps!

What’s the answer to
Roman55 [17]

Hint: the sum of the angles is equal to 180 in a triangle. could you make an equation to use that?

3x+13, 7x+2, and 75 are the three angle values. They will sum up to 180.

Steps:

We set the equation to:

3x+13+7x+2+75=180

We can combine some terms

10x+90=180

Then, we isolate x

10x=90

And we divide by 10

x=9

Great! but we are not done yet. We want the measure of angle A, so we need to plug x back into the equation for angle a

3(9)+13

Multiply

27+13

Add

40

What’s the slope of x+2y=-8?
mash [69]

Answer:

- 1/2

Step-by-step explanation:

We use the slope-intercept form to figure out our slope.

y = mx + b

Get y alone:

x + 2y = -8

2y = -x - 8

y = -x/2 - 4

Since m is the slope in y = mx + b, we can see that -1/2 is in the place of m, therefore our slope is -1/2

Y + 3y + 5y = -18 what is the value of y
ANEK [815]

Answer:

y = -2

Step-by-step explanation:

Step 1: Combine like terms.

  • (y+3y+5y)=-18
  • 9y=-18

Step 2: Divide both sides by 9.

  • 9y/9=-18/9
  • y=-2

Step 3: Check if solution is correct.

  • -2+3(-2)+5(-2)=-18
  • -2-6-10=-18
  • -18=-18

Therefore, y = -2.

What mixed number is equivalent to 18/8
sukhopar [10]
The mixed number to 18/8 is 2 and 1/4
To find this out you multiply 8 to get to 18, yet 8 only goes to 16 before going over 18, so 8 can multiply 2 times.
The 2 will be your whole number 
and since there is 2 numbers left (18-16=2) that would be the numbers left over giving you 2 2/8.
yet the 2/8 can be simplified to 1/4 giving you 2 1/4 as your answer.
Hoped this helped!
