Factor the polynomial completely. If the polynomial cannno be factored, sayit is prime

1 answer:

5 0

Ok so first, you can take out a greatest common factor, which is 2
You’ll be left with 2(x^2-3x-20)
I factored from there
Here’s my work
Hope this helps :)

Combine like terms 4a2-3b2+ 4b + 10a2

jolli1 [7]

Answer:

14a² - 3b² + 4b

Step-by-step explanation:

Like terms are the terms that have similar stuff on it, like same variables, no variables, and stuff like that.

4a2-3b2+ 4b + 10a2

4a² and 10a² is similar. 4a² + 10a² = 14a²

Now, the equation is 14a² - 3b² + 4b. There is no more like terms left, so that is the answer.

Hope this helps!!

Iteru [2.4K]

I'm pretty sure it would be 40,000 because if i'm not mistaken you meant the nearest 10,000 since the number is 39,892.

HD Straight line graphs

Taya2010 [7]

Answer:

The equation of the sraight line 3x- y+ 6 =0

Step-by-step explanation:

Explanation:-

Given that the gradient of the function

|gradf| = 3 and point (-1,3)

Given that the slope of the line

m = 3

The equation of the straight line passing through the point(-1,3) and slope m =3

$y -y_{1} = m(x-x_{1} )$

y-3 = 3(x-(-1))

y-3 = 3x+3

3x +3-y+3=0

3x- y+ 6 =0

Final answer:-

The equation of the sraight line 3x- y+ 6 =0
