Answer:
+ 10 and + 7
Step-by-step explanation:
Given
2x² + 7x + 5
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 2 × 5 = + 10 and sum = + 7

Now it's up to you which graph suites best? You will get your answer by referring it with my graph.
Hope this will help you!
I believe it’s the second one because it’s the only one that has the same variable.

Answer: B) 6</h3>
===============================================
Explanation:
Add the equations by adding the terms straight down.
The x terms add to x+x = 2x.
The y terms add to y+(-y) = y-y = 0y = 0, so the y terms go away
The constants add to 5+7 = 12
The z terms add to -z+z = 0z = 0 and those go away as well
After all that adding, we have 2x = 12 which solves to x = 6 after dividing both sides by 2.
