-18.5

Answer: - 18.65

Step-by-step explanation: Here, we have the expression 15x + 4 and we want to evaluate the expression when x = - 1.51.

To evaluate an expression, we simply plug the value of the variable into the expression and solve.

So here, since x is equal to - 1.51, we have 15 (-1.51) + 4.

15 (-1.51) is equal to - 22.65.

So we have - 22.65 + 4 which is equal to - 18.65.

So the value of our expression when x is equal to - 1.51 is - 18.65.
