<span>f(x)=x^3-4x^2+2x+4, we know that f(2)=8-16+4+4=16-16=0
and we can write f(x)= (x-2)Q(x) so Q(x) = f(x) / (x-2)=x²-2x-2
</span><span>x²-2x-2=0   delta = (-1)²- (1).(-2) =1+2=3
</span>x=1-sqrt3  or <span>x=1+sqrt3  
finally the zeros are x=2, </span>x=1-sqrt3  or <span>x=1+sqrt3 </span>

Eloise made a list of some multiples of 8/5 write 5 fractions that can be in Eloise list
alexgriva [62]
This question is asking for a list of fractions, that when you pull out common factors, they will all simplify back to the 8/5 fraction.

So if 2 is the common factor, you multiply the numerator and denominator by 2.

2: (8*2)/(5*2)= 16/10

3: (8*3)/5*3)= 24/15

4: (8*4)/(5*4)= 32/20

5: (8*5)/(5*5)= 40/25

10: (8*10)/5*10)= 80/50

Eloise's Potential List:
16/10, 24/15, 32/20, 40/25, 80/50

If you simplify any of these fractions above, you will get 8/5 again.

To work backwards:
80/50: 10 goes into 80, 10 goes into 50= 8/5

16/10: 2 goes into 16, 2 goes into 10= 8/5

Hope this helps! :)

I dont know how to solve these
Ne4ueva [31]

Answer:

137°

Step-by-step explanation:

So, both are equal to each other due to them being the same degree angle.

5x+7=8x-71

subtract 5x on both sides

7=3x-71

add 71 to both sides

77=3x

divide both sides by 3

77/3=x

x equals about 26

insert x into the problems

[5(26)+7]°

this equals 137°

[8(26)-71]°

this equals 137°
