Answer:

-9.8n+11.1

Step-by-step explanation:

You have to add all like terms. That means that -5.8n and -4n have to be added together along with 3.1 and 8. That gets you -9.8n+11.1.

Which is the completely factored form of 12x4 + 39x3 + 9x2?

Troyanec [42]

<h3><u>Explanation</u></h3>

Given expression

${12x}^{4} + {39x}^{3} + {9x}^{2}$

Factor the expression by using common factor.

We csn pull out 3x² out of the expression.

${3x}^{2} (4 {x}^{2} + 13x + 3)$

We simply pull out the x-term with lowest degree and 3 out of the expression. If another expression cannot be factored after first factoring then that's the final answer.

The expression can still be factored. Factor the expression by using two brackets.

${4x}^{2} + 13x + 3 \\ (4x + 1)(x + 3)$

New factored form

$3 {x}^{2} (4x + 1)(x + 3)$

<h3><u>Answer</u></h3>

$\large \boxed { {3x}^{2} (4x + 1)(x + 3)}$

Solve (x – 4)^2=5<br> Hhhhhbb

Oxana [17]

Answer:

x = 4 + sqrt(5) or x = 4 - sqrt(5)

Step-by-step explanation:

Solve for x:

(x - 4)^2 = 5

Take the square root of both sides:

x - 4 = sqrt(5) or x - 4 = -sqrt(5)

Add 4 to both sides:

x = 4 + sqrt(5) or x - 4 = -sqrt(5)

Add 4 to both sides:

Answer: x = 4 + sqrt(5) or x = 4 - sqrt(5)
