Answer:

5, 10, 11

Step-by-step explanation:

You could actually solve this problem 2 ways. You could use the pythagorean theorem, if you could confirm it was a right triangle.

But since they give you the perimeter, that will be the easy way.

Perimeter means all the sides added together will be 26

(x) + (x+5) + (2x+1) = 26

Now combine like terms

4x + 6 = 26

Subtract 6 from both sides

4x = 20

Divide both sides by 4

x = 5

Now we can plug the x back in the find the length of each side

(5) = 5

(5) + 5 = 10

2(5) + 1 = 11

Answer:

The left side   5

The bottom  10

The slanted side  11

Step-by-step explanation:

To find the perimeter of the triangle, add up the side lengths

x+ 2x+1 + x+5 = 26

Combine like terms

4x+6 = 26

Subtract 6

4x+6-6 =26-6

4x=20

Divide by 4

4x/4 = 20/4

x=4

The left side  x = 5

The bottom  x+5    = 5+5 = 10

The slanted side  = 2x+1 = 2*1 +1 = 10+1 =11

Substitution<br> 1.y=-5x-19<br> y=-6x-24<br><br> 2.y=-6x-22<br> y=-3x-10
omeli [17]

Answer:

1. y=5 and x=-5

2. y=2 and x=-4

Step-by-step explanation:

1.y=-5x-19

y=-6x-24

since both equations are equal to y, they are also equal to eachother

-5x-19=-6x-24

addition P.O.E.

x-19=-24

addition P.O.E.

x=-5

substitute x into one equation

y=-5*-5-19

y=6

2. y=-6x-22

y=-3x-10

since both equations are equal to y, they are also equal to eachother

-6x-22=-3x-10

addition P.O.E.

-22=3x-10

addition P.O.E.

-12=3x

division P.O.E.

-4=x

substitute x into one equation

y=-3*-4-10

y=2

tiny-mole [99]

Answer:

It would be 2

Step-by-step explanation:

Since they are looking for only 1 significant fig. you would round the number that would make this correct, for example:

You would look at 1.7 and ignore the others...

7 is greater than 5 so it'll affect the 1

And that how you get 2 : )
