здесь получается 30ха

Answer 2

To expand the expression -15x*(-2a), we can use the distributive property of multiplication over addition and subtraction. Here's the step-by-step process:

-15x * (-2a) = (-15x) * (-2) * a

To simplify further, we can multiply the coefficients (-15 and -2) and keep the variable "a" unchanged:

(-15x) * (-2) * a = 30x * a

Therefore, the expanded form of -15x * (-2a) is 30xa.
