Answer:

$\Large\boxed{\sf{9x+11}}$

Step-by-step explanation:

Given:

Isolate the term of x from one side of the equation.

Use the distributive property.

DISTRIBUTIVE PROPERTY:

$\Longrightarrow: \sf{A(B+C)=AB+AC}$

Each term within the parentheses can be multiplied by a factor outside the parentheses.

3(x+1)

3*x=3x

3*1=3

Rewrite the expression down.

3x+3

3x+3+2(3x+4)

Multiply expand.

2(3x+4)

2*3x=6x

2*4=8

6x+8

3x+3+6x+8

Combine like terms.

3x+6x+3+8

Add the numbers from left to right.

3+8=11

3x+6x+11

Add.

Solutions:

3x+6x=9x

$\Longrightarrow: \boxed{\sf{9x+11}}$

Therefore, the final answer is 9x+11.

I hope this helps. Let me know if you have any questions.

SOMEONE PLEASE HELP! THANK YOU

Answer:

arithmetic; common difference; 8

Step-by-step explanation:

Let's first define arithmetic and geometric sequences:

Arithmetic:

Arithmetic sequences are made up of successive terms that share a common difference. In other words, if the sequence is, say: a, b, c, d, then we know that: d - c = c - b = b - a

Geometric:

Geometric sequences are made up of successive terms that share a common ratio. In other words, if the sequence is, say: e, f, g, h, then we know that:

h/g = g/f = f/e (where the / denotes division)

Here, let's try applying the arithmetic sequence rule to the three terms:

2, 10, 18

18 - 10 = 8

10 - 2 = 8

Ah, we see that the common difference is indeed 8, so this is an arithmetic sequence.

Thus, the answer is: arithmetic; common difference; 8.

If x^2 = 50, what is the value of x?

SIZIF [17.4K]

X^2 = 50

Square both sides

x= √50

x= (√25)(√2)

x = 5√2

Final answer: x = 5√2 and since x is to the power of 2 you can have x = + or - x = 5√2
