HELP!!<br>Find the third term of (x^2+3y)^3

lana66690 [7]

Answer:

$T_{3}=27{x}^{2}y^2$

Step-by-step explanation:

The given binomial expression is:

$( {x}^{2} + 3y)^{3}$

When we compare to:

${(a +b)}^{n}$

We have

$a = {x}^{2}$

$b = 3y \\ n = 3$

The nth term is given by;

$T_{r+1}=^nC_ra^{n-r}b^r$

To find the 3rd term, we put:

$r + 1 = 3 \\ r = 2$

We substitute into the formula to get:

$T_{3}=^3C_2( {x}^{2} )^{3-2}(3y)^2$

We simply:

$T_{3}=3( {x}^{2} )^{1} \times 9y^2$

$T_{3}=27{x}^{2}y^2$

Answer:

$x=5\sqrt{3}$

Step-by-step explanation:

Evaluate the Pythagorean Theorem for the triangle.

a² + b² = c²

5² + x² = 10²

25 + x² = 100

Subtract 25 from both sides.

x² = 75

Square root.

x = sqrt(75)

Expand the radical.

x = 5*sqrt(3)
