Answer:
B
Step-by-step explanation:
1.6/0.2=8
10⁵-10²=10³
B, T=2L+7, Toby is 2*the age of liv plus 7 years
31 x 7.875 = 244.125
244.125 inches altogether
A line segment from a vertex to the midpoint of the opposite side is a "median". A median divides the area of the triangle in half, as it divides the base in half without changing the altitude.
AAMC is half AABC. AADC is half AAMC, so is 1/4 of AABC. (By the formula for area of a triangle.)
ABMC is half AABC. ABMD is half ABMC, so is 1/4 of AABC. (By the formula for area of a triangle.)
Then, AADC = 1/4 AABC = ABMC, so AADC = ABMC by the transitive property of equality.
