Find the perimeter of triangle PQR. Round your answer to the nearest tenth.
BabaBlast [244]
We are given the coordinate of the 3 vertices. From these coordinates we can find the length of the sides using the distance formula and the sum of all the sides will be equal to the perimeter of the triangle.

Side PQ = \sqrt{ (6-(-2))^{2}+  (1-1)^{2} }=8

Side QR = \sqrt{ (4-6)^{2}+ (-3-1)^{2} }=4.5

Side RP = \sqrt{ (2-(-4))^{2}+ (-3-1)^{2} }=7.2

So, the perimeter of the triangle will be 8 + 4.5 + 7.2 = 19.7 

You probably misplaced the digits in option A. The correct answer is 19.7 units.

What value of x is in the solution set of 4x – 12 5 16 + 8x?
TEA [102]

Answer:

4x-12= 16 +8x

And we can subtract 4x in both sides and we got:

-12 = 16 +4x

Now we can subtract in both sides 16 and we got:

-28 = 4x

And if we divide both sides by 4 we got:

x = -7

And the best solution would be:

-7

Step-by-step explanation:

For this case we assume the following equation:

4x-12= 16 +8x

And we can subtract 4x in both sides and we got:

-12 = 16 +4x

Now we can subtract in both sides 16 and we got:

-28 = 4x

And if we divide both sides by 4 we got:

x = -7

And the best solution would be:

-7
