Step-by-step explanation:

There are 6 different combinations of choices for the date:

Thai food, movie
Thai food, ice skating
Thai food, art museum
Italian food, movie
Italian food, ice skating
Italian food, art museum

An easier way to solve for this is multiply by how many choices are in each category.

In food there is 2 choices, in activities there is 3 choices

Therefore: 2 x 3 = 6

How do I answer this using the square root method? <br>-9(3x-2)^2=-225

dedylja [7]

$\bf -9(3x-2)^2=-225\implies (3x-2)^2=\cfrac{-225}{-9}\implies (3x-2)^2=\cfrac{225}{9}
\\\\\\
3x-2=\sqrt{\cfrac{225}{9}}\implies 3x-2=\cfrac{\sqrt{225}}{\sqrt{9}}\implies 3x-2=\cfrac{15}{3}
\\\\\\
3x=\cfrac{15}{3}+2\implies 3x=\cfrac{21}{3}\implies x=\cfrac{21}{9}$
