Is anyone good with triangle inequalities? I provided a picture for the problem.
alisha [4.7K]

Answer:

1 < x < 19

Step-by-step explanation:

Triangle Inequality Theorem

Let y and z be two of the side lengths of a triangle. The length of the third side x cannot be any number. It must satisfy all the following restrictions:

x + y > z

x + z > y

y + z > x

Combining the above inequalities, and provided y>z, the third size must satisfy:

y - z < x < y + z

We are given the measures y=10, z=9. The third side must satisfy:

10 - 9 < x < 10 + 9

1 < x < 19

Given g(x)=3x+6 on what interval is the function negative
iris [78.8K]

Step-by-step explanation:

A number that is negative is less than 0, so

3x + 6 < 0

3x <  - 6

x <  - 2

So this function is negative, when x is less than -2

: Solve for the variable x3+7=20 s.
german

Answer:

x = (13) ^ 1/3

x is approximately 2.351334688

Step-by-step explanation:

x^3 + 7 = 20

Subtract 7 from each side

x^3 + 7-7 = 20-7

x^3 = 13

Take the cube root of each side

x^3 ^ 1/3  = (13) ^ 1/3

x = (13) ^ 1/3

x is approximately 2.351334688
