Answer:

9n^2 - 5n

Step-by-step explanation:

(3n^3 - 5n + n^2) - (-8n^2 + 3n^3)

Lets open the brackets. Signs of all the terms in the bracket next to the minus sign will change.

=> 3n^3 - 5n + n^2 + 8n^2 - 3n^3

Now lets add/substract all the like terms with each other.

=> 3n^3  - 3n^3  + n^2 + 8n^2 - 5n

=> 9n^2 - 5n \: \: or \:\: n(9n - 5)

An angle measures 7.4° less than the measure of its complementary angle. What is the measure of each angle?
Xelga [282]

Answer:

41.3° and 48.7°

Step-by-step explanation:

Complementary angles are angles with the sum of 90°

if one of the angle is 7.4° less than other

(90 - 7.4) ÷ 2 = 41.3° is the measure of smaller angle and

41.3 + 7.4 = 48.7° is the measure of bigger angle
