The midsegment of abc is im. what is the length of mc if bc is 18 inches
long?
a. 36 inches
b. 18 inches
c.27 inches
d. 9 inches

D. 9 inches

Step-by-step explanation:

Given : The midsegment of Δ ABC is line segment IM.

Such that for side BC ,  BM=MC         [ Show in the picture ]     (1)

and BC= BM+MC    (2)

The length of BC = 18 inches              (3)

From (1) and (2), we have

Using (3), we have

Therefore, the length of MC = 9 inches.

Hence, D is the correct option.

answer: y = -12x + 108

step-by-step explanation: do (y = m x+b) formula.

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)
