5 0

Answer:

Step-by-step explanation:

x2 - 4x - 12 = 0

x2 - 6x + 2x - 12= 0

x(x - 6) + 2(x - 6) = 0

x + 2 = 0

x = - 2

x - 6 = 0

x = 6

What is the value of x? <br><br> __mm
andrezito [222]

Answer:

161.91

Step-by-step explanation:

First find the side length or YT by using the pythagorean theorem.

c= 129.2^2 = 16692.64

b= 68^2=4624

c-b = 12068.64

The square root of 12068.64 is approximately 109.86.

Using that length use the pythagorean theorem again and so:

a = 109.86^2 = 12068.64

c = 57^2 = 3249

a-c = 8819.64

The square root of 8819.64 is approximately 93.91.

So, 68 + 93.91 = 161.91
