Let, length and breadth of rectangle is L and B respectively.
It is given that :
The length rectangle is 4 cm more than 3 times the width of the rectangle.
L = 3B + 4 ......1 )
Also, area of square = area of the rectangle + 66
L² = LB + 66
Putting value of L from
L² = ( 3B + 4 )( B ) + 66
L² = 3B² + 4B + 66
( 3B + 4 )² = 3B² + 4B + 66
9B² + 16 + 24B = 3B² + 4B + 66
6B² + 20B - 50 = 0
3B² + 10B - 25 = 0
3B² + 15B - 5B -25 = 0
3B( B + 5 ) -5( B + 5 ) = 0
B = 5/3 units
L = 3( 5/3 ) + 4
L = 5 + 4 = 9 units
Hence, this is the required solution.
Answer:
x - 6
Step-by-step explanation:
A = L x W
A / L = W
x^2-11x+30 / x -5 = W (Simplify the numerator)
(x - 6) x ( x - 5) / x - 5 = W (Cancel the similar ones which is (x - 5) )
x - 6 = W
Hope that helps
Answer:
T^75
Step-by-step explanation:
3 times 5 = 15
5 times 15 = 75
2 represents the thousands. Round the number after 2 which is 6. Since 6 is greater than 5, you round it up and you get 53,000.
The answer is C 16 I believe
