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:
2x^2 -3x +10
Step-by-step explanation:
2(x^2 + 5) − 3(x + 1) + 3
Distribute
2x^2 +10 -3x -3 +3
Combine like terms
2x^2 -3x +10 -3+3
2x^2 -3x +10
Answer:
cant be factored
Step-by-step explanation:
Answer: y= 1/4 x + 500
Step-by-step explanation:
The slope is the difference in y-values divided by difference in x-values plus the starting constant value (500 on the graph)
700 - 600 is the difference in y-values = 100
800 - 400 is the difference in x-values = 400
100/400 = 1/4
y = x/4 +500
