Expand.<br> Your answer should be a polynomial in standard form.<br> (-p? - 4p - 3)(p2 + 2)
Setler79 [48]

Answer: Here is the answer.

Step-by-step explanation: we have to multiply each of the terms with the other terms.

=(-p²+4p-3)(p²+2)

=-p²*p²+ ( -p²*2) + 4p*p² + 4p*2 - 3*p²+ ( -3*2)

= -p³ -2p²+4p³+8p-3p²-6

=3p³-5p²+8p-6  (I grouped the like terms and added them)

therefore, 3p³-5p²+8p-6 is the polynomial in the standard form.

Si una llave vierte 6 1/3 litros de agua por minuto, ¿cuánto tiempo tardará en llenar un depósito de 88 2/3 litros de capacidad?
Ierofanga [76]

Answer: 14 minutes

Step-by-step explanation:

Given: A tap pours 6\dfrac13 liters of water per minute.

To find : Time taken to fill an88 \dfrac23 liters capacity tank.

which is given by :-

Time = 88 \dfrac23\div 6\dfrac13 minutes

=\dfrac{3\times88+2}{3}\div\dfrac{3\times6+1}{3}  minutes

=\dfrac{266}{3}\div \dfrac{19}{3} minutes

=\dfrac{266}{3}\times\dfrac{3}{19}  minutes

=\dfrac{266}{19}=14\text{ minutes}

Hence, it will take 14 minutes to fill an88 \dfrac23 liters capacity tank.

The drama club at Math Academy High School sold tickets to their end of the year play. On Monday they sold 80 tickets for a tota
riadik2000 [5.3K]

Answer: OPTION A

Step-by-step explanation:

Let be "a" the number of adults tickets they sold and "s" the number student of tickets they sold.

With the information given in the exercise you can set up the following System of equations:

\left \{ {{a+s=80} \atop {6a+4.5s=426}} \right.

Use the Elimination method to solve the system of equations:

1. Multiply the first equation by -6.

2. Add the equations.

3. Solve for "s" in order to find its value.

Then:

\left \{ {{-6a+-6s=-480} \atop {6a+4.5s=426}} \right.\\............................\\-1.5s=-54\\\\s=36

4. Finally, substitute the value of "s" into the first equation and solve for "a":

a+36=80\\\\a=80-36\\\\a=44
