HELP PLEASE!!! WORTH 8 points!!!!

1 answer:

7 0

It seem like it's listing the factors and not the roots. If the given factors are x-2, x-(1+sqrt(5)), and x+3i

Then this means that x-(1-sqrt(5)) is another factor. So it looks like choice B is the answer. I'm using the idea that if x-(a+b*sqrt(c)) is a factor then so is x-(a-b*sqrt(c)).

Answer:

A) 5.4 cm

Step-by-step explanation:

Length of mid segment = (sum of parallel sides )/2

Sum of parallel sides = PQ + SR = 9 + SR

$\frac{9+SR}{2}=MN\\\\\frac{9+SR}{2}=7.2 cm\\9 +SR = 7.2*2\\\\9 + SR = 14.4\\ SR = 14.4 -9 \\SR = 5.4 cm$
