Please help! i suck at math, please please help me.

ok so first you would recognize both parantheses have no liked terms within them selves so what you would do is add like terms from both parantheses

Step-by-step explanation: so 12y + y = 13y , 20y^2 - 13y^2 = 7y^2 beacuse the 20y^ is the greater integer, then lastley your left with -10 and -2 just combine those you get -12, so your answer would look like

(13y + 7y^2 - 12)

2500

step-by-step explanation:

the square root of what number? if you add that, then someone will probably answer the question.
