Answer 1

The value of the expression 3x(3.2-1.8)-0.8 is 7.6 when x = 2.

Step-by-step explanation:

To evaluate the expression 3x(3.2-1.8)-0.8, we can substitute the value of x into the expression and simplify.

Let's assume x = 2, then:

3x(3.2-1.8)-0.8 = 3(2)(3.2-1.8)-0.8 = 6(1.4)-0.8 = 8.4-0.8 = 7.6

So, when x = 2, the value of the expression is 7.6.
