Answer:

y = 130°

Step-by-step explanation:

4x + 8 + x + 7 + 3x - 19 = 180 (all angles in a triangle add upto 180)

8x = 184

x = 23°

3x - 19 + y = 180 (supplementary = 180)

sub x = 23 into equation

50 + y = 180

y = 130°

Need help with this math problem

Andre45 [30]

Hey There!

First you would need to factor out the two.

-4x^3/2 = -2x^3

2x^2/2= x^2

12x/2= 6x

6/2= 3

Now we have.

-2x^3+x^2+6x+3 / x+1

We would then factor with polynomial division, and then we should have.

-2(2x^2 - 3x - 3)(x+1) / x+1

We would then cancel out the x+1

Therefore, the answer would be $\boxed{-2(2x^2-3x-3)}$

Hope this helped!

pshichka [43]

Since there is no way to determine what is asked from the given above, I assumed that it is the total earning from the sales of the aluminum cans. To answer, multiply the mass of aluminum cans in kilograms to the price of 1 kilogram of cans. Example, if there are x kilograms of aluminum cans, the total earning would be $0.002x.
