PLEASE HELP ME FIND THE MISSING LENGTH ITS URGENT .

37

Step-by-step explanation:Using the Pythagorean Theorem, a ² + b ² =c ², you substitute the values for a and b with 12 and 35. This makes your equation 12 ² +35 ² = c ² . You then add 12 ² with 35 ² and that gives you 37 ² = C ² . You find the square root of both sides which is 37=C, giving you the length of C.

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x
