If 2/√3+√5 + 5/√3-√5 = a√3 +b√5 find a and b

2/√3+√5 + 5/√3-√5 = a√3 +b√5

Add fractions.

7/√3+2√5

To have √3 in numerator multiply both sides of raction by √3.

(7√3)/3+2√5 = a√3 +b√5, thus a = 7/3 and b = 2:

Make sure you wrote the equation write, because Im not sure about that.

step-by-step explanation:

once you graph it hit 2nd (the blue button) and graph

that takes you to a table of coordinates

on the left is x coordinates and on the right is y coordinates and an empty box

(you may have to scroll up/down in order to get ( x, 0)

the best buy, is the 4- kilogram bag of lollipops for $18.40.

step-by-step explanation:

i found my answer by dividing the cost of each bag by their respective weights.

18.4 divided by 4 = 4.6

24.4 divided by 5 = 4.88

by this, i found that the 4 kilo bag is the best buy.
