Question 2 Factorise completely:
2.2 a²-7a-30
2.4 -8a³+8a
2.6 15x⁴-15y⁴
2.8 2(x-y)²-x+y

​

lo.lll

step-by-step explanation:

35-60 students are taking math.

let y equal to

the total fare and x is the mile of taxi ride. so the equation is

y = 0.55x + 1.75

since susie has

$10 to spend for a taxi cab, so he can have

10 = 0.55x +

1.75

x = 15 miles of

taxi ride

so the system of

inequality is

10 < 0.55x +

1.75

x > 2

im with everythinglos so yeahhhhh
