Answer:
P(x) = (x-1)² (x-3)
Step-by-step explanation:
P(x)=x³- 5x² + 7x-3 = x² (x-1) - 4x(x-1) + 3(x-1) = (x²-4x+3)(x-1)
P(x) = (x-1)(x-3)(x-1) = (x-1)² (x-3)
There were 80 questions on the test.
1. First of all, this is a isosceles triangle, meaning measurement I=58°, which makes it way easier to find T.



1. m{t}°=64 m{I}°=58
