Answer:

A. 12x^{4} -4x^{3} +3x^{2} +3x+20

Step-by-step explanation:

For this problem, we have to combine like terms.

Let's look at the equation:

(12x^{4} -4x^{3} +7x+6)+(3x^{2} -4x+14)

12x^{4, -4x^{3}, 3x^{2} do not have any other like terms, so we keep all in the final answer.

7x and -4x are like terms, so we combine them. 7x-4x=3x

14 and 6 are like terms, so we combine them. 14+6 = 20

Let's put everything into the final equation:

12x^{4} -4x^{3} +3x^{2} +3x+20

So, the final answer is A. 12x^{4} -4x^{3} +3x^{2} +3x+20

8+35/w=15<br>a.8<br>b.6<br>c.10<br>d.5​
RoseWind [281]

Answer:

\boxed{ \bold{ \huge{ \bold{w = 5}}}}

Option D is the correct option

Step-by-step explanation:

\sf{8 +  \frac{35}{w}  = 15}

⇒\sf{ \frac{8 \times w + 35}{w}  = 15} { w ÷ 1 = w , So, I wrote 8 × w }

⇒\sf{ \frac{8w + 35}{w}  = 15}

Apply cross product property

⇒\sf{8w + 35 = 15w}

Move 15w to left hand side and change it's sign

Similarly, Move 35 to right hand side and change it's sign

⇒\sf{8w - 15w  =  - 35}

Collect like terms

⇒\sf{ - 7 w =  - 35 }

Divide both sides of the equation by -7

⇒\sf{ \frac{ - 7w}{ - 7}  =  \frac{ - 35}{ - 7} }

Calculate

⇒\sf{w = 5}

Hope I helped!

Best regards!!
