The equivalent expression is - 25n - 2 and it matches with option D.

Step-by-step explanation:

We have to simplify and create the equivalent expression for

{- 2(- 5n + 6) + 5(2 - 7n)}

Now, {- 2(- 5n + 6) + 5(2 - 7n)}

= 10n - 12 + 10 - 35n

= - 25n - 2

Therefore, the equivalent expression is - 25n - 2 and it matches with option D. (Answer)

quit

step-by-step explanation:

given : the shape of his satellite can be modeled by   where x and y are modeled in inches.

now,the given equation   is a equation of parabola.

here, coefficient of x is positive, hence the parabola opens rightwards.

on comparing this equation with standard equation , we get

in standard equation, coordinates of focus=(0,m)

thus for given equation coordinates of focus=(0,1.5)
