D control, the researchers are creating a control group that experience all of the same conditions of the test group (receiving a pill) but receive no benefit of the vitamin. It helps to reduce variable in the study to determine validity
Answer:
x = 18
Step-by-step explanation:
The "Angle Bisector" Theorem says that an angle bisector of a triangle will divide the opposite side into two segments that are proportional to the other two sides of the triangle.
So, 20/8 = (4x + 3)/30
8(4x + 3) = 20(30)
32x + 24 = 600
32x = 576
x = 18
B. is correct! Hope this helps!
