Question

На отрезке СD отмечены точки М и N так что точка М Лежит между точками C и N. Найдите:Длину отрезка CD если CM =12 см MN больше CM на 6 см а CM меньше NDна 4 см

Answer 1

MN = 12 + 6 = 18 см
ND = 12 + 4 = 16 см
CD = 12 + 18 + 16 = 46 см

Answer 2

Given Information

We are given the following information: - Point M lies between points C and N on the line segment CD. - CM = 12 cm. - MN is 6 cm longer than CM. - CM is 4 cm shorter than ND.

Solution

To find the length of segment CD, we need to determine the lengths of CM, MN, and ND.

Let's assign variables to the unknown lengths: - Let x be the length of MN. - Let y be the length of ND.

From the given information, we can set up the following equations: 1. MN = CM + 6 cm 2. CM = ND - 4 cm

We can substitute the value of CM from equation 2 into equation 1: MN = (ND - 4 cm) + 6 cm

Simplifying the equation: MN = ND + 2 cm

Now, we can express the length of CD in terms of CM, MN, and ND: CD = CM + MN + ND

Substituting the values we have: CD = 12 cm + (ND + 2 cm) + ND

Simplifying the equation: CD = 12 cm + 2 ND + 2 cm

To find the length of CD, we need to determine the value of ND.

Unfortunately, the given information does not provide enough information to determine the value of ND. We would need additional information or equations to solve for ND and find the length of CD.
