Explanation for Question 1 From the Math (Calc) Section on the 2018 March Sat
Question one asks, which of the following is equivalent to the expression above. 2 So to figure out which expression is equivalent, 3 I'm going to need to distribute. 4 So three X times two X is six X squared. 5 Plus three X, times three is nine X plus two times 6 two X is four X plus three times two is 7 six. And then I can add and subtract like terms to get six X 8 squared plus not extra sports together is 13 X plus 9 six. And that's answer choice C.
