What is the answer to <br> 24=3(n−5)
-Dominant- [34]
3(n - 5) = 24

Distributive property

3*n = 3n
3*5 = 15

3n - 15 = 24
      + 15  +15

3n = 39
3n/3 = 39/3
x = 39/3
x =  13

Answer: x = 13

Can I have help with this, I have drawn out a graph and marked my points so far.
Sidana [21]

Answer:

D. 2x²

Step-by-step explanation:

Ok, so the first thing to do is remember the first number in parentheses is x, and the second number is y.

You're trying to figure out which expression turns x into y in each set.

Just by plugging in the numbers into each expression I found that the answer is 2x².

I'll prove this starting with (1, 2).

1² = 1  

2 x 1 = 2

So, y = 2x²!

Next, (2, 8).

2² = 4

2 x 4 = 8

So, y = 2x²!

I'm not going to demonstrate with the other two but I hope you understand. Just plug the values of x and y into the equation and see which is correct.

Factor 3a^3 + 18a² + 8a + 48 completely.
fomenos

Answer:

(3a2 + 8) • (a - 6)

Step-by-step explanation:

STEP 1:

Equation at the end of step 1

 (((3 • (a3)) -  (2•32a2)) +  8a) -  48

STEP  2:

Equation at the end of step 2:

 ((3a3 -  (2•32a2)) +  8a) -  48

STEP 3:

Checking for a perfect cube

3.1    3a3-18a2+8a-48  is not a perfect cube

Trying to factor by pulling out :

3.2      Factoring:  3a3-18a2+8a-48

Thoughtfully split the expression at hand into groups, each group having two terms :

Group 1:  8a-48

Group 2:  -18a2+3a3

Pull out from each group separately :

Group 1:   (a-6) • (8)

Group 2:   (a-6) • (3a2)

              -------------------

Add up the two groups :

              (a-6)  •  (3a2+8)

Which is the desired factorization

Polynomial Roots Calculator :

3.3    Find roots (zeroes) of :       F(a) = 3a2+8

Polynomial Roots Calculator is a set of methods aimed at finding values of  a  for which   F(a)=0  

It would only find Rational Roots that is numbers  a  which can be expressed as the quotient of two integers

The Rational Root Theorem states that if a polynomial zeroes for a rational number  P/Q   then  P  is a factor of the Trailing Constant and  Q  is a factor of the Leading Coefficient

In this case, the Leading Coefficient is  3  and the Trailing Constant is  8.

The factor(s) are:

of the Leading Coefficient :  1,3

of the Trailing Constant :  1 ,2 ,4 ,8

Hey can anyone please help with this
g100num [7]

Step-by-step explanation:

Among these three options , Option B is the correct answer.

GF||JK

So,m<F= m<K. ( alternate interior angles)

and , m<G= m<J. (alternate interior angles)

so ∆FGH similar to∆KJH
