Answer:

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

Step-by-step explanation:

x^3 + x^2 + 3x + 3

Factor an x^2 out of the first group of 2 terms and a 3 out of the last group of 2 terms

x^2 (x+1)  +3(x+1)

Now factor out an (x+1)

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

Answer:

8x +3

Step-by-step explanation:

Just collect the like terms, like terms have the same variable. So in this case, 2x, 3x, 3x all share the variable x, so we can add it together.

So when simplified:

2x +3x + 3x+ 3 = 8x +3

Hope this helped,

Answer:

Step-by-step explanation:

The y intercept is where x = 0.

X and y are both increasing by 5.

If you add five to the bottom row of the table we see that the next row of the table is x = 0 and y = 13.

This means that (0,13) is the y-intercept and 13 is your correct answer.

icang [17]

Answer:

V = 128π/3 vu

Step-by-step explanation:

we have that: f(x)₁ = √(4 - x²);  f(x)₂ = -√(4 - x²)

knowing that the volume of a solid is  V=πR²h, where R² (f(x)₁-f(x)₂) and h=dx, then

dV=π(√(4 - x²)+√(4 - x²))²dx;  =π(2√(4 - x²))²dx ⇒

dV= 4π(4-x²)dx , Integrating in both sides

∫dv=4π∫(4-x²)dx , we take ∫(4-x²)dx and we solve

4∫dx-∫x²dx = 4x-(x³/3) evaluated -2≤x≤2 or too 2 (0≤x≤2) , also

∫dv=8π∫(4-x²)dx evaluated 0≤x≤2

V=8π(4x-(x³/3)) = 8π(4.2-(2³/3)) = 8π(8-(8/3)) =(8π/3)(24-8) ⇒

V = 128π/3 vu

Given the following system of equations: −x + y = 2 2x + 4y = 32 What action was completed to create this new equivalent system
tiny-mole [99]

Answer:

you just need to devide by 2 the second equation

Step-by-step explanation:

  • -x + y = 2 (you leave it as it is)

  • 2x + 4y =32 => 2x/2 +4y/2 = 32/2

=> x + 2y =16

we can devide or multiply in an equation by any number we want, as long as we do it to every term.

Suppose the circumference of a circle is 4, pi. What is its diameter?
Vilka [71]
Your answer would be 4, because the equation for the circumference of a circle is π × diameter, so if you have 4 × π as the circumference, then 4 is the diameter.

I hope this helps!
