Answer:
6
Step-by-step explanation:
Since you're familiar with your multiplication tables, you know that ...
42 = 6 × 7
There are 6 tiles in each of the 7 rows.
11+(2×4)
11+8
$19....
580
4*100=400
4*40=160
4*5=20
add them all up, you get 580
The gradient is -2.
The gradient = rise/ run
= (0-6)/(3-0)
= -6/3
= -2.
