Answer:
x^3-2x^2-13x+6
Step-by-step explanation:
We are to simplify the expression (x+3)(x^2−5x+2). This is as shown;
(x+3)(x^2−5x+2)
Expand
= x(x^2)-5x(x)+2x+3x^2-3(5x)+6
= x^3 - 5x^2+2x+3x^2-15x+6
Collect the like terms
= x^3 - 5x^2+3x^2+2x-15x=6
= x^3-2x^2-13x+6
This gives the required expression
Answer:
226.22 in^2
Step-by-step explanation:
Given data
Height l= 6in
Diameter= 12in
Radius= 12/2= 6in
The expression for the total surface area of a cone is given as
TSA= πrl+πr^2
substitute
TSA= 3.142*6*6+3.142*6^2
TSA= 113.112+113.112
TSA= 226.22 in^2
Hence the TSA is 226.22 in^2
