Answer: D. 4
Step-by-step explanation:
In the given picture , we have given a triangle ΔMLN in which
ML= 4x and MN= x+3
∠L=∠N=50°
⇒ MN=ML [∵ Basically by Isosceles triangle property :sides opposite to equal angles of a triangle area equal.]

Subtract x from both sides , we get

Divide bothe sides by x , we get
1= x or x =1
Then, the length of MN
= x+3=1+3=4 units
Answer: center = (-3, 2) radius = √23
<u>Step-by-step explanation:</u>
The equation of a circle is: (x - h)² + (y - k)² = r²
where center = (h, k) and radius = r
Complete the square for both x and y:

You would subtract x from both sides . then divide the whole equation by 2. your new equation would be y=-1/2x+5 . the graph would going downwards, the line would intercept the y axis at 5, and you would go down one unit and over two units. [to graph it]
