Answer:
c. 528000
Step-by-step explanation:
The computation of the amount that need to be paid is shown below:
Let us assume the side of the square shaped hall be X meter
s
So,
Perimeter = 4X
Now
4X = 400
X = 100m
Now
Area of the hall = 100 × 100 = 10000 sq. meter.
And,
The cost on total tiles is
= 10,000 × 48 = Rs. 480000
But, there is 10% damage has occurred that involved in the cost
So,
Total cost is
= Rs 480,000 + 10% of 480,000
= 480,000 + 48,000
= Rs. 5,28,000
Answer:
4x^2 +1656x + 1261
Step-by-step explanation:
X multiply by 4x is 4x^2 (4x squared)
x multiply by 7 is 7x
4x^2+7x
97 x 17x is 1649x
97 x 13 is 1261
1649x+1261
4x^2 + 7x + 1649x + 1261
1649x + 7x is 1656x
4x^2 +1656x + 1261
Answer:
-4x -10x
See both terms contain a common multiple x
and HCF of 4 and 10 is 2
So, take -2x common
-2x( 2 +5)
= -2x(7)
=-14x
