Answer:
can not be expressed as a square of any other number.
Step-by-step explanation:
The number 1953125 is equal to .
Now, the above statement gives an idea that 1953125 i.e. is not a square number as 9 is not a multiple of 2.
So, we can not express as a square of any other number.
We can only express 
as 
.
( Answer )
Smallest side XYZ/ Smallest side ABC = Longest side XYZ/ Longest side ABC
Let longest side XYZ be x
280/112 = x/144
x = (280/112)×144
x = 360
Option D will be your answer

Answer:
The cost of spoon is £1.84 and therefore the cost of one knife is £5.52.
Given :
-
A knife is 3 times the cost of the spoon.
- 9 spoons and 12 knives costs £82.80.
Solution :
-
This question is solve by creating a linear equation and linear equations are nothing but yet another subset of "equations".
- Linear calculations that requires more than one variable can be done with the help of linear equations.
- The standard form of a linear equation in one variable is ax + b = 0.
Now let x be the cost of spoon. Than the cost knife is 3x. It is given that 9 spoons and 12 knives costs £82.80.
<h3>
</h3>
Therefore the cost of 1 knife = 5.52
Step-by-step explanation: 
You need to have variables one one side and constants on the other. ax - ax + by = c - ax
by = c - ax
by/b = (c - ax)/b
y = (c - ax)/b
