Question

1) c(B+2a) 2) m(1-m) 3) 3x(4y-z) 4) 5(a в квадрате -2aBв квадрате

Answer 1

1.cb+2ac

2.m-m в квдрате

3.12xy-3xz

4.5a в квадрате - 10ab в квадрате

Answer 2

It appears that you have provided a list of mathematical expressions. Let's simplify each of them:

1. c(B + 2a): To simplify this expression, we distribute the 'c' to both terms inside the parentheses: c(B + 2a) = c * B + c * 2a = cB + 2ac

2. m(1 - m): To simplify this expression, we distribute the 'm' to both terms inside the parentheses: m(1 - m) = m * 1 - m * m = m - m^2

3. 3x(4y - z): To simplify this expression, we distribute the '3x' to both terms inside the parentheses: 3x(4y - z) = 3x * 4y - 3x * z = 12xy - 3xz

4. 5(a² - 2aB²): To simplify this expression, we apply the distributive property: 5(a² - 2aB²) = 5 * a² - 5 * 2aB² = 5a² - 10aB²

Keep in mind that the above answers are simplified expressions, but if you have any specific values for the variables (e.g., 'a', 'b', 'c', 'm', 'x', 'y', 'z'), you can substitute them into the simplified expressions to get numerical results.
