Photo has the work you need
1. Take the two x-axis intersections.
For Q 31 it is:
x = -4 and x = 0
2. Reorganise the previous equations
x +4 = 0 and x = 0
3. Put the x side in brackets
x(x+4)
4. Done

Q 32
x = -1
x = 5
x + 1 = 0
x - 5 = 0
(x+1)(x-5)
Answer:7cm
Step-by-step explanation:

Answer:
Average = 16, standard deviation =
Step-by-step explanation:
15+12=27
27+(17+14)+22=27+31+22=80
80/5=16
Distance from 22 to 16=6, from 12 to 16=4, so deviation = 5
