Answer:

-6x^2+4x+5

Step-by-step explanation:

g(x)+f(x)=(-8x^2-3x+5)+(2x^2+7x)

=-8x^2-3x+5+2x^2+7x

=-8x^2+2x^2-3x+7x+5

=-6x^2+4x+5

Answer:

- 5

Step-by-step explanation:

Note that - (- 12) = + 12

Thus

- 17 - (- 12) = - 17 + 12 = - 5

It looks like Tom subtracted 12 from - 17, that is - 17 - 12 = - 29

-5+7q+ -5q+ -9q please help

vekshin1

For this case we must simplify the following expression

$-5 + 7q + (- 5q) + (- 9q)$

We know that, by definition:

$+ * - = -$

So, rewriting the expression we have:

$-5 + 7q-5q-9q =$

We add similar terms taking into account that:

Equal signs are added and the same sign is placed.

Different signs are subtracted and the major's sign is placed:

$-5 + 2q-9q =\\-5-7q$

Answer:

$-5-7q$
