10] James is about to paint the walls of his lounge. The lounge has 4 walls (2 x Wall A and 2 x Wall B). Wall A and wall B which has a square window of side 1.0m, are shown below: Wall A Wall B
3.0m
4.0m
5.0m
A can of paint advertises coverage of 4.5 m2. How much paint will James require?

yes. we do proportions in probabilities.

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)  

answer: (3,11) is your answer.
