Afunction is shown.
f (x) = 3x2 + 4x + 1

Factor completely. 4p^2 + 36p + 81 express the answer in the form (ap + b)^2

The angles below are supplementary. what is the value of x? a pair of supplementary angles is shown. one angle measures 7x + 33, and the other angle measures 70. 5.3 8.14 11 14.7

Can someone check if i did this correct. it’s number 4 if you’re wondering.
