Rationalise this please.
it's verey imp to me.

Step-by-step explanation:

i) root3 + root5 × 2root5 / 2root5 × 2root5

= 2root15 + 10 / 20

ii) root3 - root7 × root3 - root7 / root3 + root7 × root3 - root7

= 3 - 2root21 + 7 / 3 - 7

= 10 - 2root21 / -4

= -10 - 2root21 / 4

iii) root2 + root7 × 2root2 + root3 / 2root2 - root3 × 2root2 + root3

= 4 + 2root14 + root6 + root21 / 8 - 3

= 4 + 2root14 + root6 + root21 / 5

i need a picture

step-by-step explanation:

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .
