Пошаговое объяснение:

-5a + 8 * 1 + 8 * 3a = -5a + 8 + 24a = 19a + 8

Answer 2

To solve the expression -5a+8(1+3a), we can use the distributive property of multiplication over addition, which states that:

a(b+c) = ab + ac

Using this property, we can expand the expression as follows:

-5a + 8(1+3a) = -5a + 81 + 83a = -5a + 8 + 24a

Next, we can simplify the expression by combining the like terms (i.e. the terms with the same variable "a"). In this case, we have -5a and 24a, so we can add them together to get:

-5a + 24a = 19a

Therefore, the simplified expression is:

-5a + 8(1+3a) = 19a + 8

So the final answer is 19a + 8.
