1. c = 13
2. a = 20
Step-by-step explanation:
1. 12² + 5² = x²
144 + 25 = x
144 + 25 = 169
√169 = 13
2. 29² - 21² = x²
841 - 441 = x
841 - 441 = 400
√400 = 20

Answer:
x<_-2 ( x is less than or equal to -2)
Step-by-step explanation:
First remove opposites and collect like terms so it will be -4x+12+4x<_-8x-8x-20.
Then move them to be 12<_-16x-20.
Move -16x to the left and the 12 to the right to combine it with -20 to become -32.
You are now left with 16x<_-32.
Divide both sides by 16 to get x<_-2.
Hope this helped :) btw <_ is less than or equal to i just dont know how to put the sign on top of the underscore :/
