Analyze and explain why a = a, and a = b determines how many solutions there are to a given equation. 8. Andrea wrote two
different simplified expressions. Each expression had the same coefficient (the number
multiplying the variable). If she sets the expressions equal to each other, will the equation have one solution, no
solution or infinitely many solutions? Explain your answer using an example to support your reasoning.

Asap for seven months an ice creams vendor collects data showing the number of cones sold a day (c) and the degrees above 70 degrees f the vendor finds that there is a positive linear association between c and t that is the best modeled by this equation c=3.7t+98 which statement is true? the model predicts that the average number of cones sold in a day is 3.7 the model predicts that the average number of cones sold i a day is 98 a model predicts that for each additional degree that the high temperature is above 70 degres f the total of number of cones sold increases by 3.7 the model predicts for each additional degree that the high temperature is above 70 degrees f the total number of cones sold increasingly by 98

Which one ? is the answer and how to find this answer

Which expression is equivalent to (4 +6i)^2? ? -20 + 48i 8 + 12i 16 - 36i 20 + 48i
