Answer:
26
Step-by-step explanation:
3x^2 + 7x
when x = 2,
=> 3(2)^2 + 7(2)
=> 3(4) + 14
=> 12 + 14
=> 26
Answer:
slope
Step-by-step explanation:
Answer:
41, x=-5
Step-by-step explanation:
m<DEY = m<FEY, by angle bisector theorem
(9x-4) = 41
9x = 45
x = 5
m<DEY = 41
Remember the properties of logarithms. If you have ln81, you can pull out the power of two (9^2) and have 2ln9. Also, you could do ln9 + ln9 because 9*9=81 and ln9*9 = ln9 + ln9
With these properties, you can get 3lnx+2lny, which is 3u+2v according to the answer.
Hope I helped!
