Answer:

Option 3) 24 is right.

Step-by-step explanation:

Given in the picture is a triangle LMN. sides are MN = 12, LN = 21 and LM = x cm

Also MO is the angle bisector of angle M.

By applying angle bisector theorem for triangles we get

LM/MN = LO/NO

i.e. x/12 = 14/7

Simplify to get x = 24

Hence option 3 is right

Verify:

Check whether angle bisector theorem is true.

The proportion LM/MN =24/12 = 2

The proportion LO/NO =14/7 =2

Both are equal and hence verified

Find the domain of f(x) = - squareroot x^2 - 4

erma4kov [3.2K]

Answer:

d. x ≥ 2 or x ≤ -2

Step-by-step explanation:

The domain is the set of all possible x-values that will make the function work.

For the function to work, the radicand cannot be negative.

x² - 4 ≥ 0

x² ≥ 4

x ≥ 2 -x ≥ 2

x ≤ -2

The domain is x ≥ 2 and x ≤ -2.

The graph of your function shows that ƒ(x) does not exist when -2 < x < 2.

What is r+s+t when r = 26, s = –12, and t = –8? a. 6 b. 22 c. 30 d. 46

Allisa [31]

All you have to do to solve this problem is insert the integer for the variable in the expression.

So, instead of having the variable expression r+s+t, you would have the integer expression 26-12-8.

If you combine 26 and -12, you get 14-8.

If you subtract 14-8, you get 6.

Your final answer is a. 6.
