In the diagram below, x is a whole number. what is the smallest possible value for x?

lesya692 [45]

Answer:

The smallest possible value for x is $9\ units$

Step-by-step explanation:

we know that

The <u>Triangle Inequality Theorem</u>. states that the sum of the lengths of any two sides of a triangle is greater than the length of the third side

$x+x>17\\2x>17\\x>8.5\ units$

The value of x must be greater than $8.5\ units$

If x must be a whole number

therefore

The smallest possible value for x is $9\ units$

How many solutions does the equation 3x + 6 = −1 − 3 + 4x have

VashaNatasha [74]

Answer:

ONE: x = 10

Step-by-step explanation:

3x + 6 = -1 - 3 + 4x

3x + 6 = -4 + 4x |subtract 6 from both sides

3x = -10 + 4x |subtract 4x from both sides

-x = -10 |change the signs

x = 10
