Answer:
Step-by-step explanation:
Begin by grouping the x terms and the y terms together and separating the constants out.

Now we'll complete the square on those x and y terms. Take half the linear term of each, square it, and add it to both sides. Our linear x term is 2, half of 2 is 1 and 1 squared is 1, so we add that in. Likewise, half the linear y term (which is 8) is 4, and 4 squared is 16, so we add that in, too. Like this:

Doing this gives us the perfect square binomials for each of the x and y terms, and then gives us the radius on the right:

This is a circle with a center of (1, 4) and a radius of 3.
Hey there! I happy to help!
Here's how to find the distance between any two points.
Find the difference between the x values.
-4-3=-7
Square it.
-7²=49
Find the difference of the y values.
6-(-7)=6+7=13
Square that.
13²=169
Add up the two numbers you got.
169+49=218
And square root it.
√218≈14.76.
Have a wonderful day! :D
The answer is B because the formula for area of a triangle is (B*H)/2= A
(5*4)/2= A
20/2=A
10=A
Answer:
x= 56
Step-by-step explanation:
86+94= 180 which if supplementary angles have to equal 180°
I don't know if you can tell but what's in red means distribute
then I added 26 on both sides with like terms
on the left side 86+26=112 and right side is left with 2x
then divide both sides by 2 to leave x by itself
112/2= 56 and 2x/2=x
so 56=x
