(a^3 - 2a + 5) - (4a^3 - 5a^2 + a - 2)

− 3 a ^3 + 5 a ^2 − 3 a + 7

Step-by-step explanation:

Apply the distributive property.

a ^3 − 2 a + 5 − ( 4 a ^3 ) − ( − 5 a ^2 ) − a −  − 2

Simplify.

a ^3 − 2 a + 5 − 4 a ^3 + 5 a ^2 − a + 2

Simplify by adding terms.

Subtract  4 a ^3  from  a ^3 .

− 3 a ^3 − 2 a + 5 + 5 a ^2 − a + 2

Subtract  a  from  − 2 a .

− 3 a ^3 − 3 a + 5 + 5 a ^2 + 2

Simplify the expression.

Add  5  and  2 .

− 3 a^ 3 − 3 a + 5 a ^2 + 7

Move  − 3 a .

− 3 a ^3 + 5 a ^2 − 3 a + 7

I hope this helped. I am sorry if you get this wrong.

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
