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.
