-u≥4−u≥4 true. Then write an equalivalent inequality, in terms of uu. (Numbers written in order from least to greatest going acr
ziro4ka [17]

Answer:

(a)\ u \le -4

(b)\ u =\{-\infty,.....,-6,-5,-4\}

Step-by-step explanation:

Given

-u \ge 4

Solving (a): An equivalent inequality

We have:

-u \ge 4

Multiply both sides by -1 (this changes the inequality)

-u*-1 \le 4 * -1

u \le -4

Solving (b): Values of u from least to greatest

u \le -4 implies that u ends at -4, starting from negative infinity

So, the list is:

u =\{-\infty,.....,-6,-5,-4\}

A triangle has two sides with lengths 31 centimeters and 39 centimeters. Which best describes the length of the third side? A. l
PilotLPTM [1.2K]

Answer:

D. greater than 8 cm and less than 70 cm

Step-by-step explanation:

Given:

Length of one side = 39 cm

Length of other side = 31 cm

We need to find the length of third side.

Solution:

to find the length of third side we will use triangle Inequality property which states that;

"The length of the third side should be less than sum of the other two side."

Also;

"The length of the third side should be greater than difference of the other two sides."

Now Sum of 2 sides of triangle = 39 + 31 =70 cm

Also Difference of 2 side of triangle = 39 -31 = 8 cm

Hence The length of the third side should be greater than 8 cm and less than 70 cm.
