Step-by-step explanation:

Convert 10% to a decimal by dividing by 100:

10/100 = 0.10

Multiply list price by decimal percent:

3.30 x 0.10 = 0.33.

Subtract discount amount from list price:

3.30 - 0.33 = 2.97

Subtract discount amount from list price:

65.00 - 13.00 = 52.00

What is the simplified form of the following expression?(x10)(x2) x8 x12 x20 x100

notka56 [123]

I believe the answer would be x20. Between the two parentheses there's a multiplication symbol. So you would just pretend that the parentheses aren't there cause the variable(s) (x) is/are like terms. So you would just multiply 10 times 2 and put out the x back in front of it
