a) FALSE (would be TRUE if it said LN(56)-LN(7)=LN(8))
b) TRUE (because LN(x+y)-LN(x+y)=LN[(x+y)/(x+y)]=LN(1)=0)
This is right solution:
12^2+9^2=The third side^2
144+81=The third side^2
225=The third side^2
√225=The third side
15=The third side
Hope it helps....
<span>What you do is just multiply $56.53 by 1.17. That represents 117% (100% for the meal and 17% for the tip).
Hope that helps! You should get $66.1401, but since you cant have a hundredth of a penny, its just $66.14. :)</span>
