Answer:
Ooh is theis unions I did it but
So firstly, what two terms have a product of 8x^2 and a sum of 9x? That would be x and 8x. Replace 9x with x + 8x: 
Next, factor x^2 + x and 8x + 8 separately. Make sure that they have the same quantity on the inside: 
Now you can rewrite the equation as 
Now using zero product property, solve for x:

<u>In short, the solutions are {-1,-8}, or C.</u>
Answer:
Margarita gastó <u>$40.43.</u>
Step-by-step explanation:
Tenemos la siguiente información.
<u>km recorridos por Margarita</u>
42 km - ciudad
387 km - autopista
<u>Rendimiento del carro</u>
1 galon cada 28 km - ciudad
1 galon cada 36 km - autopista
Hacemos el siguiente factor de conversión
<u>Ciudad</u>

<u>Autopista</u>

Ahoa, se sabe que 1 galon cuesta $3.30. Por lo tanto, el costo de viaje será:
Total galones = 1.5 + 10.75 = 12.25 galones
Total costo = 3.30*12.25 = $40.43.
