so next 3 numbers in the given sequence are 43 , 52 and 61
Divide 756 by 3 to find out how many calories is burned per hour.
756 / 3 = 252
prove this by doing
252 * 3 = 756
Therefore, Vivi burns 252 calories per hour.

Answer:
Step-by-step explanation:
(a). 
= x ( 2x + 1 ) = <em>2x² + x</em>
(b). 
= 2( 2x + 1 )( 5x + 3 ) = <em>20x² + 22x + 6</em>
(c). 
= 20x² + 22x + 6 - ( 2x² + x ) =
( 20x² - 2x² ) + ( 22x - x ) + 6 =
<em>18x² + 21x + 6</em>
