Consider the trinomial 6x2 + 13x + 6.
the value of ac is
.
the value of b is
.
the two numbers that have a product of ac and a sum of b are 4 and

the value of ac is 36

the value of b is 13

the two numbers that have a product of ac and a sum of a and b are 4 and 9

47 - 90 = 43

43 - 180 = x

x = 137

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
