Find the difference: sqrt20-sqrt80

-2sqrt5

Step-by-step explanation:

Lets begin by simplifying the radicals.

20 can be factored into 4*5, and since 4 is a perfect square, we can take out a 2.

therefore:

sqrt20 = 2sqrt5

80 can be factored into 16*5, and since 16 is a perfect square, we can take out a 4

therefore:

sqrt80 = 4sqrt5

So finally we have, 2sqrt5-4sqrt5 = -2sqrt5

hey there!

if she's saving for six months, let's divide the total number we need for the trip by six, dividing it into the amount that needs to be saved for each month.

500 ÷ 6 =

she needs to save at least this amount each month, so we should use this symbol: ≥

let x be the amount she saves each month.

your final answer is x ≥

hope this !

4 candies

step-by-step explanation:

7 x 28 = 196

200 - 196 = 4 candies remaining.
