B and D are correct because the graph cuts the x-axis twice and therefore has 2 roots whihc is the samme as 2 solutions

the equation in A is correct if you factorise it and find solution x= 3.5 or x=1 as shown where it cuts x axis

C is false. It cuts x axis at 3.5 and 1 not -1.5 and -3

n=9

step-by-step explanation:

7 times a number = 7n

2n=18

n=9
