Answer:

3x^{2}-4x+12

Step-by-step explanation:

In this case we have to simplify the expression by giving it in the standard polynomial format, first we have to see what is the polynomial standard format, this is:

ax^{2} +bx+c

In the case of the expression presented we have to make the multiplications and additions to then organize the expression:

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

First the multiplications:

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

Now the additions and organization:

3x^{2}-4x+12

Now we have the expression in the polynomial format.

pishuonlain [190]

Answer:

b.

Step-by-step explanation:

30×0.5×63 = 945

this is not a square number. therefore, the sqrt(945) is a number of infinite digit positions after the decimal point without repeating pattern.

so, it is a prime example of an irrational number.

You and a friend start riding bikes toward
Setler [38]

Answer:

1.5 hours

I traveled farther

2 miles

Step-by-step explanation:

\text{Speed}=\dfrac{\text{Distance}}{\text{Time}}

My speed

\dfrac{2\dfrac{1}{6}}{\dfrac{1}{4}}=\dfrac{\dfrac{13}{6}}{\dfrac{1}{4}}=\dfrac{26}{3}\ \text{mph}

Speed of my friend

7\dfrac{1}{3}=\dfrac{22}{3}\ \text{mph}

Time passed for both me and my friend will be equal if we start at the same time and the combined distance covered by both of us will be 24 miles. Let t be the time taken to meet

\text{Distance}=\text{Speed}\times\text{Time}

\dfrac{26}{3}t+\dfrac{22}{3}t=24\\\Rightarrow \dfrac{48}{3}t=24\\\Rightarrow 16t=24\\\Rightarrow t=\dfrac{24}{16}\\\Rightarrow t=1.5\ \text{hours}

So, we meet each other after 1.5 hours.

Distance traveled by me

\dfrac{26}{3}\times 1.5=13\ \text{miles}

Distance traveled by my friend

\dfrac{22}{3}\times 1.5=11\ \text{miles}

So, I traveled farther by 13-11=2\ \text{miles}.
