Answer:
C=13
Step-by-step explanation:
Pythagorean theorem
a^2 + b^2=c^2
a squared plus b squared equals c squared
-7x+14>-3x-6
add 7x to each side
14> 4x-6
add 6 to each side
20>4x
divide by 4
5>x
x<5
solutions
3,0,-3,-5,-10
10/10
2.5
Put the values in place of the corresponding variables and do the arithmetic:
ab - 0.5b = (1)(5) -0.5(5) = 5 - 2.5 = 2.5
-> 3rd answer is correct
