<span>3x + 3 = 78
3x = 75
x = 25
So the three numbers are 25, 26, and 27. </span>

Even consecutive numbers are 2 apart
(2,4,6, example)
so they are
n,n+2,n+4
their sum is 78
n+n+2+n+4=78
3n+6=78
minus 6
3n=72
divide 3
n=24
smallest is 24

What is the length of the longest side of a triangle that has vertices at (7, 6), (7, 1), and (-5, 6)?
iren2701 [21]

Answer: The Answer is going to be B.

Step-by-step explanation:

We can find the distance between each pair of points using the distance formula Sqrt((x1-x2)^2 + (y1-y2)^2),(x1 and x2 are the x ordinates of each point, and y1 and y2 are the y ordinates. Sqrt stands for square root, and ^2 is to the power of two.

Using this we can find the side between 7,6 and 7,1 is 5.

The side between 7,1 and -5,6 is 13

The side between 7,6 and -5,6 is 12

After using the formula we can conclude the side between 7,1 and -5,6 is the longest, and it equals 13. Therefore the answer is B.

Which set of rectangular coordinates describes the same location as the polar coordinates (6sqrt 2, 3pi/4)
Sonja [21]
Polar coordinates=<span>(6sqrt 2, 3pi/4)=(r, theta)→r=6 sqrt 2, theta=3pi/4
Rectangular coordinates=(x,y)=?

x=r cos theta=(6 sqrt 2) cos(3pi/4)=(6 sqrt 2)(-sqrt 2 / 2)
x=-3 (sqrt 2)^2=-3(2)→x=-6

y=r sin theta=(6 sqrt 2) sin (3pi/4)=(6 sqrt 2)(sqrt 2 / 2)
y=3 (sqrt 2)^2=3(2)→y=6

Rectangular coordinates of the point = (x,y) =(-6,6)

Answer: Option a. (-6,6) </span>
