<span>The identity element when applied does not change the other elements hence in multiplication 1x7=7 and 1x5=5 the elements 5 and 7 do not change for addition its 0 such as 0+10=10.

I think it would be more because when you multiply 4*2 it'll be 8
Find the surface area of the 4 walls by doing
2(8.5x3.4) + 2(6.5x3.4)
Then subtract the area of the 2 doors , which is 4
So the total painted surface will come out to be 98m
Multiply 98 by the cost, £160 to get a total cost of £15680 to paint the room
70% is not equivalent but 60% is
The answer is (x-7) (x+1)
