The first one is the answer/
Answer:
If the underlined digit is 5 then it is Fifty thousand (50,000)
Answer=10:40
Explanation:
Don’t know how to type the symbol in font of the 50 so I will substitute
£50=$50
So 1:4
Add it up
1+4=5
So 5 total units
$50=5
Divided by 5
$10=1 units
So 1:4=10:10 times 4=10:40
Length = x + y
Area of a square = Length x Length
The expression can be :
1) Area of the square = (x + y)(x + y)
2) Area of the square = (x + y)²
3) Area of the square = x² + 2xy + y²
