Answer:

See below

Step-by-step explanation:

The ratio of the secants is the same when set up as full length to external length.

Formula

MN/LN = QN/PN

Givens

LN = 22 + 14 = 36

MN = 14

PN = 32

QN = x

Solution

14/36 = x / (32)  Multiply both sides by 32

14*32 / 36 = x    Combine 14 and 32

448/36 = x         Divide by 36 and switch

x = 12.4

Answers

PN (External) = 13 is the closest answer

Length LN = 36

Answer:

Hope it helps!

Step-by-step explanation:

Sub y=5x into y=2x+3

so

5x=2x+3

3x=3

x=1

plug x=1 into y=5x

y=5

Checking work

Plug (1,5) into y=2x+3

5=2(1)+3

5=5

Plug (1,5) into y=5x

5=5(1)

5=5
