Answer: x = 8

             MN = 52

             LK is congruent to LM

             LN is  congruent to NL

ΔKLN and ΔMLN have:

LN ≅ LN

∠K = ∠M = 90°

∠KLN = ∠MLN

=> ΔKLN ≅ ΔMLN

=> KN = MN

=> 7x -4 = 5x + 12

⇔ 2x = 16

⇔ x = 8

=> KN = MN = 7.8 - 4 = 52

How to you solve x2 -20x -17 = -53
Gennadij [26K]

Answer:

solve for x

x=2

Step-by-step explanation:

x2-20x-17=-53

reorder like terms x2= 2x       2x=20x-17=-53

collect like terms 2x-20x=-18x           -18x-17=-53

move constant to the right hand side and change its sign   -18x=-53+17

calculate the sum -53+17= -36         -18x=-36

divide both sides by -18  -18x÷-18= x        -36÷-18=2

x=2

--8x < 32. How can I solve this
Vlada [557]

Answer:

<u>Divide by -8</u> on both sides. <u>Flip</u> the inequality.

Step-by-step explanation:

You didn't provide any answer choices, but here's how you would solve this:

-8x < 32\\\\\frac{-8x}{-8} < \frac{32}{-8}\\ \\x > -4

Notice that because we divided by a negative, the inequality sign must flip in the other direction!
