Yeah the answer is 16.
And could I get brainiest because I need to get it one more time to get to my next rank
345 in Standard Form is 3.45 x 10^2
This is because when in standard form the decimal should move to the right 2 times.
7x^2 - x = 6
7x^2 - x - 6 = 0
(7x + 6 )(x - 1) = 0
7x + 6 = 0; x = -6/7
x - 1 = 0; x = 1
answer
x = -6/7; x = 1
