PLEASE HELP! I NEED THE ANSWERS TODAY Express 18√8 in the form a√b where a and b are integers and b is as small as possible.

Hint(s): Factor sqrt(8) as the product of two square roots, one of which is the square root of a perfect square.

PLEASE HELP!!!

Explanation:

This radical can be simplified.  You know that the number inside of the radical; 8, is the product of 4 and 2.  You know that 4 is a perfect square (2 times 2).  Therefore, you can leave the 2 on the inside and the 4 on the outside.  You now must multiply the 18 on the outside of the radical by 2 because you must take the square root of the original 4 you had.  Therefore, you answer will be .

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

hope this
