Answer is 1704 and to explain just put that you added to get your final answer
Step-by-step explanation:
If f = price of filing cabinet and c = price of cupboard we can make up the equation
2f + 4c = 800
we also know that f = 3c, so can substitute that into equation
2 (3c) + 4c = 800
6c + 4c = 800
10c = 800
c = 80
f = 240
Answer:
There is no answer.
Step-by-step explanation:
There is no square root of -1. Although 1 can be derived from 1x1, 1 is not the square root of 1 as positive 1 x positive 1 will always give a positive 1. Similarly, negative 1 x negative 1 will always give a positive 1 hence it is not possible for -1 to have a square root.
