Which is the completely factored form of 12x3 – 60x2 + 4x – 20?
2 answers:
Completely factored it is (12x^2 + 4)(x-5)
= 4(3x^3 - 15x^2 + x - 5)
product of first coefficient and -5 is -15 so one factor could be x +/ 3) or x +/- 5)
using the factor theorem f(5) = 375 - 375=5-5 = 0 so (x - 5) is a factor:-
so we have 4(x - 5)(3x^2 + 1) Answer

Step-by-step explanation:
[5(14-2)^2]/2=
(5•12^2)/2=
5•144/2=
5•72=
720/2= 360
The product of this is 90
Answer:
all the angles add up to 180 degrees
So 180÷6=30
(i got 6 cuz 1+2+3)
so 1=30
2=30*2=60
3=30*3=90
