Factor: 3x^2 - 288y^2 - 36

erica [24]

Answer:

3x^2-288y^2-36

Rewrite -36 as 12×3

Rewrite -288 as 96×3

3x^2+96.3y^2+12.3

factor out common term 3

=3(x^2-96y^2-12)

Consider a bag of jelly beans that has 30 red, 30 blue, and 30 green jelly beans. a) How many color combinations of 15 beans hav

igor_vitrenko [27]

Answer:

680

Step-by-step explanation:

Number of red beans = 30

Number of Blue beans = 30

Number of green beans = 30

How many color combinations of 15 beans have at least 6 green beans?

Since at least 6 of the beans must be green,

Then (15 - 6) = 9

Then, the remaining 9 could be either red, blue or green.

Therefore, C(9 + (9 - 1), 3)

C(17, 3) = 17C3

nCr = n! ÷ (n-r)! r!

17C3 = 17! ÷ (17 - 3)! 3!

17C3 = 17! ÷ 14!3!

17C3 = (17 * 16 * 15) / (3 * 2)

17C3 = 4080 / 6

17C3 = 680 ways

Solve the following exponential equation <br><img src="https://tex.z-dn.net/?f=3%20%7B%7D%5E%7B2x%20%7D%20%20-%209%20%3D%200" id

77julia77 [94]

Answer:

x = 1

Step-by-step explanation:

Given exponential equation:

$3^{2x}-9=0$

Add 9 to both sides of the equation:

$\implies 3^{2x}-9+9=0+9$

$\implies 3^{2x}=9$

$\textsf{Apply exponent rule} \quad a^{bc}=(a^b)^c:$

$\implies \left(3^2\right)^{x}=9$

$\implies9^{x}=9$

$\textsf{Apply exponent rule} \quad a=a^1:$

$\implies9^{x}=9^1$

$\textsf{Apply exponent rule} \quad a^{f(x)}=a^{g(x)} \implies f(x)=g(x):$

$\implies x=1$
