Answer:
-2<x<1
Step-by-step explanation:
That's all it can go I think.
Answer:
1. 4.5x
2. 4.5x+12=48
3. x=8
Step-by-step explanation:
4.5(8)+12=48
36+12=48
48=48
Answer:
p = -4 q = 2
Step-by-step explanation:
- Expand the brackets ( yes the entire thing).
- group together the values with same co-effiecients; like (q+p)x^3 etc etc.
- equate the co-effiecients on the left hand side to the now grouped ones on the right, for example [x^3]: -2x^3= (q+p)x^3, the x^3 cancels and ull get an equation only in terms of p and q. do the same for [x] and ull get an equation with only q, solve this and get the value for q [q = 2].
- sub in this value for the [x^3] equation and ull get an answer for p [p= -4].
hope my explanation is understandable lol
