Apple: £20
Banana: £60
I believe this is the answer because between the two problems there is a difference of £60. So I saw three apples were gone from the next so 60 divided by 3 is 20. Then we need to find the banana price. 20 x 7 = 140. 200 - 140 is 60. So the banana is 60 and the apples are 20.
Answer: a+b = -2
B. -2
Because if a = 1 and b = -3 then
(2x+a)(2x+b)=4x^2-4x+ab
Plug in a = 1 and b = -3 into (2x+a)(2x+b) then solve
(2x+a)(2x+b)
= (2x + 1)(2x - 3)
= 4x^2 + 2x - 6x - 3
= 4x^2 - 4x - 3 (so ab = - 3)
