Question

4x+2(0,5+3) при x=-1,2

Answer 1

4х+1+6=4*(-1.2)+1+6=-4.8+1.+6=2.2

Answer 2

4x+1+6=4*(-1.2)+5=0.8

Answer 3

To evaluate the expression 4x + 2(0.5 + 3) when x = -1.2, we substitute the value of x into the expression and simplify:

4(-1.2) + 2(0.5 + 3)

= -4.8 + 2(3.5)

= -4.8 + 7

= 2.2

Therefore, when x = -1.2, the expression 4x + 2(0.5 + 3) evaluates to 2.2.
