I don’t understand, please help.

The diagram is showing the length of each line segment.

• NM has length 110 + 4x

• ML has length x + 103 (this is the one you have to find)

• LK has length 70

• NK has length x + 243

The segment NK has length equal to the sum of the lengths of NM, ML, and LK. So we have

x + 243 = (110 + 4x) + (x + 103) + 70

Solve this equation for x :

x + 243 = (110 + 103 + 70) + (4x + x)

x + 243 = 283 + 5x

x - 5x = 283 - 243

-4x = 40

x = 40/(-4)

x = -10

Now solve for x + 103 by adding 103 to this result:

x + 103 = -10 + 103 = 93

So ML has length 93.

the answe i =−n+5

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
