The product of 7 and a number is greater than 42. If the number is a whole number less than 10 , what could the number be?

8 or 9

Step-by-step explanation:

Your primary equation that they gave you is ?b and has to be greater than ?a  7 x ?a =42

So your answer to ?a is 7 because 7 x 7 =42   therefore your answer to ?b has to be 8 or above.  

the next part of your problem states that it is a whole number UNDER 10  this limits your possible answer to either 8 or 9.

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
