Answer:
(2x+1)(x+7)
Step-by-step explanation:
Guess and Check
(2x+7)(x+1) = 2x^2+9x+7. NOPE
(2x+1)(x+7) = 2x^2+15x+7. YES
9x-5y=11
<span>Move all terms containing x to the left, all other terms to the right.
now add 5y to each side and now it should look like this:
</span><span>9x + -5y + 5y = 11 + 5y
Now divide each side by 9 and the answer is....
</span><span>Simplifying
x = 1.222222222 + 0.5555555556y</span>
Well, if you have a 41% percent, then you would most likely get a 40%.
70's are bad grades, and lower your grade down (or at least in my school). If, though, this was a huge thing, then you would get a 39%.
I suggest you try hard on this, so your grade could increase if you get an A.(;
