A child has a box of candies which might have a toy inside. The odds against the box having a toy are 7/2 . What is the probability of the box having a toy?

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.

Idon't take stuff like this new to me

Value for line ac: (3x+6)+(2x+14)= 5x+20
