x(x)+x(2)+7(x)+7(2)
x^2+2x+7x+14
x^2+9x+14
So a=9 and b=14
The answer is d because if you multiply-5x2 and then subtract 1 you get -11

<u>Answer:</u>
Ella will need 6 lemons for 4 times the recipe
<u>Explanation:</u>
Given Ella used ¾ of a bag of lemon to make ½ liters of lemonade

bag
Lemons required for 1 liter lemonade =
= 3/2 bags
To make 4 times the recipe, she will require,

She will need 6 lemons for 4 times the recipe
(x² -5x+4) / ,(x-1). ,=. (,x-1)(x,-4) ,/ (x-1)
= (x-4)
