Can someone explain how to factor a trinomial that doesn't have a GCF? example: 2x^2+7x-15 or 6x^2+x-40

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.

10 - 75

step-by-step explanation:

there's nothing attached so it's most likely anything in that range.

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.

it has to have an angle of 90 degrees
