Factor completely 8y^3+16y^2
gregori [183]

Answer:

8y^2(y + 2)

Step-by-step explanation:

The given expression is 8y^3 + 16y^2

Let's find the greatest common factor of 8y^3 and 16y^2

The GCF is 8y^2. Let's take out the GCF outside and write the remaining terms as follows

8y^2 (y + 2)

Therefore, the factors are 8y^2 and (y + 2)

That is 8y^3 + 16y^2 = 8y^2(y + 2)

Thank you.

PLEASE HELP ASAP<br><br> Why was the Mexican-american war just or unjust. Explain with facts.
N76 [4]
As a result of the war, the Tejanos, Nuevo Mexicanos, and Californianos lost their homeland.

Please help will mark brainliest for the right answer
hodyreva [135]

Answer:

a).  x + y + 90° = 180°

b).  x = 67°

    y = 23°

Step-by-step explanation:

The sum of all angles in a triangle is 180°.

One of the angles in the figure is a right angle, or 90°.  Therefore the sum of the three angles in the figure is:

x + y + 90 = 180

We are also told that x + 2 = 3y.  

Rearranging that to isolate x gives us:  

x = 3y - 2

Thake the first equation and substitute the above expression of in place of x:

x + y + 90° = 180°

(3y-2) + y + 90° = 180°

4y + 88° = 180°

4 y = 92°

y = 23°

To find angle x, use y = 23°

x = 3y - 2

x = 3*(23°) - 2

x = 67°

The sum 90° + 67° + 23° = 180°
