To estimate I would do 50*7 which is 350. That is overestimating since the real answer is 336.
Step-by-step explanation:
I think we have to find the factors so
3x2 + 42x + 105
First we will multiply 105 by 3 = 315 then find factors of 315 which may add or subtract = 42
So 45 and 7
3x2 + 45x - 7x + 105
3x( x + 15) - 7(x - 15)
(3x - 7) and ( x - 15) are the factors
There is a problem please recheck the question
Answer:
It is 1,225 or just 1225.
6x-8=8x-10 then 2=2x which means x=1
