Answer:

-a - 7

Step-by-step explanation:

Add like terms to simplify the expression:

2a + 5 - 3a - 12

Add together 2a and -3a:

2a - 3a = -a

Add together 5 and -12:

5 - 12 = -7

Add these together:

-a - 7

So, the simplified expression is -a - 7

La distancia en Km. De Santo Domingo a Puerto Plata está dada por la expresión D = 4x³- 10x² -6. ¿Cuál es la distancia aproximad
neonofarm [45]

Answer:

The distance when x = 6km is D = 498 KM

Step-by-step explanation:

Here, given the formula for the distance, we want to find the distance D given the value of x to be 6km

What we do simply here is to substitute the value 6km as x in the equation

The equation is

D = 4x^3 - 10x^2 -6

Substituting x = 6, we have

D = 4(6^3) -10(6^2) -6

D = 864-360-6

D = 498 km
