Answer:

<X =48

<Y =96

<Z = 36

Step-by-step explanation:

The three angles of a triangle add to 180 degrees

3.2n + 6.4n +2.4n = 180

Combine like terms

12n = 180

Divide each side by 12

12n/12 =180/12

n =15

<X = 3.2 n = 3.2 *15 =48

<Y = 6.4 n = 3.2 * 15 =96

<Z = 2.4 n = 2.4 * 15 =36

Answer:

<X = 48°

<Y = 96°

<Z = 36°

Step-by-step explanation:

<X +<Y+<Z = 180

3.2n + 6.4n + 2.4n = 180

12n = 180

n = 15

<X = 3.2(15) = 48

<Y = 6.4(15) = 96

<Z = 2.4(15) = 36

Find the coefficient of the 4th term in expansion of (x +2 )^5

LuckyWell [14K]

$(x + 2)^5=(x+2)^2\cdot{(x+2)^2}\cdot{(x+2)}\\\\(x+2)^5=(x^2+4x+4)\cdot{(x^2+4x+4)}\cdot(x+2)$

$(x+2)^5=(x^4+8x^3+24x^2+32x+16)\cdot(x+2)$

$(x+2)^5=x^5+10x^4+40x^3+80x^2+80x+32$

15 Solve for y<br>| 3x - 8y = 24

rewona [7]

Answer:

$\quad y=-\frac{24-3x}{8}$

Step-by-step explanation:

1. Subtract 3x from both sides

3x-8y-3x=24-3x

2. Simplify

-8y=24-3x

3. Divide both sides by -8

$\frac{-8y}{-8}=\frac{24}{-8}-\frac{3x}{-8}$

4. Simply again to get answer.

X^2 + x^2=6^2 what is x

nikitadnepr [17]

Answer:

x = ±3 sqrt(2)

Step-by-step explanation:

x^2 + x^2=6^2

Combine like terms

2x^2 = 6^2

Divide each side by 2

x^2 = * 6^2/2

Take the square root of each side

sqrt(x^2) =± sqrt( 6^2/2)

Remember that sqrt(a/b) = ±sqrt(a ) /sqrt(b)

x = ±sqrt(6^2)/sqrt(2)

x = ±6 /sqrt(2)

We do not leave square roots in the denominator, so we multiply the top and bottom by sqrt(2)

x = ±6 /sqrt(2) * sqrt(2)/ sqrt(2)

x = ±6 *sqrt(2) /( sqrt(2)*sqrt(2))

x = ±6 sqrt(2) /(2)

x = ±3 sqrt(2)
