Answer:

11C4 × 11C5

$\binom{11}{4} \times \binom{11}{5} = \frac{11 \times 10 \times 9 \times 8}{4 \times 3 \times 2 \times 1} \times \frac{11 \times 10 \times 9 \times 8 \times 7}{5 \times 4 \times 3 \times 2 \times 1} = 330 \times 462 = 152460$

Find x, y, and z. ⠀⠀⠀⠀⠀⠀⠀⠀

fomenos

Answer:

Not sure but :

Y=15/7

X=13/5

Z=26/7

I will check them later and tell you if they are right or not .

Step-by-step explanation:

y power 2 : 31 × 8 = 248

Rad 248 = 15/7

x power 2 : 23 × 8 = 184

Rad 184 = 13/5

31 power 2 : (15/7) power 2 + z power 2

961 = 246/49 + z powe 2

z power 2 = 714/51

rad 714/51 = 26/7

z = 26/7

Step-by-step explanation:

easy

180 is a triangle

exterior+interior=180

so 180-123

To get a student learner's permit to drive in New Jersey, an individual must be at least 16 years old. Let, a, represent the age

vredina [299]

Answer:

$a\geq 16$

Step-by-step explanation:

Let $a$ represents the age at which a person gets a student learner's permit to drive in New Jersey.

Also, an individual must be at least $16$ years old to get a student learner's permit to drive in New Jersey.

So, inequality is $a\geq 16$

(Inequality explains a relationship of greater than or greater than or equal to or less than, or less than or equal to between two mathematical expressions)

12n^3 + 16n^3 can someone please help me with this?

vodka [1.7K]

Answer:

$4n^{3} (3n^{2} + 4)$

Step-by-step explanation:

Assuming the problem is asking you to factor out the formula, it can be done easily by finding a common number with the two givens.

4 goes into both 12 and 16 evenly, so we will use this to factor. But that's not all, we have the n-variable to worry about.

Look at the n-variable exponents in the problem, take the highest power that can go be subtracted from both and use that. We have a $n^{5}$ and $n^{3}$ . Since 5 can't go into 3, we must use 3 to factor.

Our factoring variable will therefore be $4n^{3}$ . Now, use this to simply divide and get the answer:

$( 12n^{5} + 16n^{3} ) / 4n^{3} = 4n^{3}(3n^{2} + 4)$

So how did we get this? For the whole numbers, we have to divide: (12/4, 16/4). Next, we have to minus the exponents since we are dividing.

When dividing the 12 and 4, minus the $n^{5}$ and $n^{3}$ to get $n^{2}$ . Get rid of the $n^{3}$ term for the 16 and leave the 4. And there's your answer!
