Use pythagorean theorem
a^2 + b^2 = c^2
fill in known values
12^2+9^2 =c^2
simplify
144 + 81 = c^2
225 =c^2
square both sides
15 = c= hypotenuse
Answer:
Step-by-step explanation:
First, we need to subtract 6 from each side, so that we can begin to isolate r.

Answer:
I cant really see any answer but if I had to simplify, then the answer would be 2t - 8 + 1, which would then be simplified to 2t - 7.
Have a nice and wonderfull day.

Answer:the percent of increase in price is 7.69%
Step-by-step explanation:
The yearbook was sold for $26 at the beginning of the year. This means that the initial price of the year book was $26.

28 - 26 = $2
The percent of increase in price would be
Increase/initial price × 100
It becomes
2/26 × 100 = 7.69%
