The centroid is where the medians, or lines from one angle to the midpoint of the opposite side, meet. This point is the center of mass and balance (D) of a triangle.
Answer:
-6xy-18x
Step-by-step explanation:
To solve -2x(3y+9), multiply -2x by 3y and 9.

This is a pretty bad question but I think the answer they're looking for is
angle
circle
line segment
We define arcs in terms of circles and parallel lines in terms of lines (though not necessarily line segments, so this is a bit of a judgement call).
Answer:
The correct option is d.
Step-by-step explanation:
The directional hypothesis is:
The sample size is, <em>n</em> = 40.
The significance level is:
Use the t-table to compute the right-tailed t-critical value as follows:
The value is positive since the directional hypothesis suggests that the test is right tailed.
The correct option is d.
Well the area of the triangle is 18 so Id figure if my math is correct x = 3
