x=7

Step-by-step explanation:

You can observe in the figure that the triangle JKL and the triangle MNP are similar, then, you can set up the following proportion:

\frac{MN}{JK}=\frac{MP}{JL}

You can identify that:

JK=25\\MN=30\\\\JL=20\\MP=4x-4

Knowing this, you can substitute values:

\frac{30}{25}=\frac{4x-4}{20}

The final step is to solve for "x" in order to find its value.

Then, you get this result:

(20)(\frac{30}{25})=4x-4\\\\\frac{600}{25}=4x-4\\\\24+4=4x\\\\\frac{28}{4}=x\\\\x=7

n inequality compares two values, showing if one is less than, greater than, or simply not equal to another value. a ≠ b says that a is not equal to b. a < b says that a is less than b. a > b says that a is greater than b. (those two are known as strict inequality)
