<span>-3(1+6r)=14-r
-3 - 18r = 14 - r ...expand by using distributive property
-3 -17r = 14 ...add (r) to both sides
-17r = 17 ...add (3) to both sides
     r = -1 ....divide both sides by (-17)</span>

Answer:

x = 4 sqrt(5)

Step-by-step explanation:

Since this is a right triangle, we can use the Pythagorean theorem

a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse

8^2 + x^2 = 12^2

64+ x^2 =144

Subtract 64 from each side

x^2 = 144-64

x^2 =80

Take the square root of each side

sqrt(x^2) = sqrt(80)

x = sqrt(16*5)

x = 4 sqrt(5)

Sergeu [11.5K]
I looked it up, it says eq triangles have 3 sides. An isos triangle is one with 2 equal sides. Every eq triangle is isos, but not every isos triangle is equilateral. I think the statement in the photo is true.

Two sides of a triangle have lengths 4 and 8. Which of the following can NOT be the length of the third side? A. 5 B. 6 C. 4 D.
Jobisdone [24]

Answer:

Step-by-step explanation:

4

If you put 4 with another 4 the total is 8. The two lines must be greater than the third. Equal is not good enough.

The other lengths will produce triangles with 4 and 8. Any 2 will be greater than the third.
