Answer: 1050
Step-by-step explanation: you multiply 10 by 7 by 15 and there is your answer.
You are given the area of both cupboards.
The total area would be found by adding the two areas together:
3a^2 − 5y + 15 + 4a^2 + 5y + 5
Combine like terms:
3a^2 + 4a^2 = 7a^2
-5y + 5y = 0y
15 +5 = 20
The area of both cupboards would be 7a^2+20
The range will be all ur y values...just as the domain is all the x values
so ur range is {5,6 }...notice that even though they repeat, u only have to list them once
