Find ML, JK=3x+11, ML=10x-12, NP=45
tigry1 [53]

Answer:

ML = 58

Step-by-step explanation:

Given

JK=3x+11, ML=10x-12, NP=45

See attachment

Required

Length ML

First, calculate x using the following equivalent ratios

JK : NP = NP : ML

Express as fraction

\frac{JK }{ NP} = \frac{NP }{ ML}

Cross Multiply

JK * ML = NP * NP

Substitute values:

(3x +11) * (10x - 12) = 45 * 45

Expand

30x^2 - 36x + 110x - 132 = 2025

30x^2 +74x - 132 = 2025

Collect like terms

30x^2 +74x - 132 - 2025=0

30x^2 +74x -2157=0

Using a calculator:

x \approx -10 and x \approx 7

Given that:

ML=10x-12

Substitute values for x

ML=10*-10-12 = -100 - 12 = -112

ML=10*7-12 = 70 - 12 = 58

ML cannot be negative; So:

ML = 58
