Answer:
A. Less than 25.
Stepbystep explanation:
Let x represent 3rd side of triangle.
We have been given hat two sides of a triangle have lengths 10 and 15.
We will use triangle inequality theorem to find the 3rd side of the triangle. Triangle inequality theorem states that 3rd side of a triangle must be less than the sum of other two sides of triangle.
Using triangle inequality theorem, we can set following inequalities:
Therefore, the length of third side should be greater than 5.
Therefore, the length of third side should be less than 25 and option A is the correct choice.

Answer:
x=3.5
Stepbystep explanation:
To solve for x , we need to make same base on both sides
9 can be written as 3^2
27 can be written as 3^3
[tex[](3^2)^{x  2} = 3^3[/tex]
multiply the inside exponent with inside exponent
Both sides have same base 3
so we equation the exponents
add 4 on both sides
divide by 2 on both sides

Hi Brainiac
5x+2=6x+11
Before we know if it is true or false the first thing we need to do is to solve the equation
5x+2=6x+11
Combine like terms
5x6x=112
x=9
Divide both sides by 1
x/1 = 9/1
x=9
Now we gonna replace 9 everywhere we find x
5x+2=6x+11
5(9)+2= 6(9)+11
45+2 = 54+11
43 = 43
Yes The equation is true because as you can see the both sides of the equation equal to each other.
I hope that's help and good luck :)
Please if you have question(s) about something you don't really understand you can just ask and I will try my best.
Have a great summer :)
