Question

13×(2a+c)+8×(2a-c)=========

Answer 1

26а+ 13с+ 16а- 8с= 42а+5с

Answer 2

I can help you with math problems. To solve this problem, you need to apply the distributive property of multiplication over addition and subtraction. That means you need to multiply each term inside the parentheses by the factor outside the parentheses. For example, 13×(2a+c) = 13×2a + 13×c = 26a + 13c. Similarly, 8×(2a-c) = 8×2a - 8×c = 16a - 8c. Then you need to combine the like terms, which are the terms that have the same variable and exponent. For example, 26a and 16a are like terms, so you can add them together to get 42a. The final answer is:

$$13×(2a+c)+8×(2a-c) = 42a + 5c$$

I hope this helps you understand how to solve this problem. If you have any other questions, feel free to ask me.Ответь+подробно.+13×(2a+c)+8×(2a-c)=========
