(5a^2+6a+2)-(7a^2-7a-5)
krok68 [10]

For this case we must simplify the following expression:(5a^ 2 + 6a + 2) - (7a^ 2-7a-5) =

We eliminate the parentheses taking into account that:

- * + = -\\- * - = +

So:

5a ^ 2 + 6a + 2-7a ^ 2 + 7a + 5 =

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 sign is placed.

5a ^ 2-7a^2 + 6a + 7a +2 +5 =\\-2a ^ 2 + 13a + 7

Answer:

-2a ^ 2 + 13a + 7

If f(x) = x-1/3 and g(x) = 3x+1 what is (fog)(x)
marin [14]

Answer:

if you meant  f(x) = (x - 1) /3    then   f (g(x) ) = x

of if you meant  f(x) = x - (1/3) then  f(g (x)) =   3x + 2/3

Step-by-step explanation:

f(x) = x-1/3 and g(x) = 3x+1 what is (fog)(x)

f ( g(x) ) =  (3x + 1)  - (1/3) =   3x  + 2/3

Or

if you meant  f(x) = (x - 1) /3    then   f (g(x) ) = x

of if you meant  f(x) = x - (1/3) then  f(g (x)) =   3x + 2/3
