Step-by-step explanation:
1) The area of rectangle is ( 30x²y + 20xy ) cm² and its breadth is 10xy cm .Find its length....
= Solution ,
Length ( L ) = ?
breadth ( b ) = 10xy cm
area ( a ) = ( 30x² + 20xy )
Now ,
area ( a ) = l × b
or, ( 30x²y + 20xy ) = L × 10xy cm
2) Subtract the quotient when 20x⁴y² is divided by 5x³y from the product of 2x and 3y.
= Solution,
The product of 3x and 4y = 6xy
= 6x - 4xy

Think about this, f(x) -> f(3). Look at the chart, x is 3. What number is directly to the right of 3. Your answer is 9.
In order to find 150% of something, you would add half of the value to itself. so for example, 150% of 9 would be 13.5 because 4.5 is half of 9 and 4.5 • 9 is 13.5. hope this helps!!
He rode his bike for 45 min a day for 6 days that means he rode 270 min in total. And the total he worked out was 360 min that week.
360 - 270 = 90
Now you divide by 6 because of the days he worked out.
90 divided by 6 = 15.
