Answer:

  the sides are different lengths as shown in the diagram

Step-by-step explanation:

Plotting the three points, you can see by "inspection" that the middle length side (PQ) is longer than the shortest side (QR) and shorter than the longest side (PR). You could use the distance formula to show this, or you can use a scale to measure the drawing.

A triangle with three unequal sides is a scalene triangle. ∆PQR is scalene.

a= 6-2b-3c

then put that equation inside the first one and then the second one

you get -6*(6-2b-3c)+2b-3c=23

and 5*(6-2b-3c)+4b-3c=-12

14b-15c=59

14b-18c=18/*(-1)

If you flip 2 coins, what is the probability of getting exactly 2 heads
Ahat [919]

Answer:

This states that the probability of the occurrence of two independent events is the product of their individual probabilities. The probability of getting two heads on two coin tosses is 0.5 x 0.5 or 0.25.

Step-by-step explanation:

The probability of getting 2 heads with 2 coins can be broken into 2 steps:

The first coin must show Heads AND

the second coin must show Heads.

p(h,h)= P(H) <----- and means multiply

P(H) x P(H)= 1/2 x 1/2 =1/4

tester [92]

Hello there!

Answer: ⇒ C. -30

_________________________________________________________

Step-by-step explanation:

First you had to remove parenthesis.

-7*4-|-6|+|4|

Then you multiply by the number.

=-28-|-6|+|4|

Apply absolute value.

|-6|=6

=-28-6+|4|

Again apply absolute value.

|4|=4

=-28-6+4

Simplify it's should be the correct answer.

=-30
