Пошаговое объяснение:

-7,5xy

15ax

-2,4by

Answer 2

To simplify the given expressions, we can apply the multiplication rules for algebraic terms.

1. -6x * 1.25y: Multiply the coefficients (-6 and 1.25) and multiply the variables (x and y) together.

Result: -7.5xy

2. 7.5a * 2x: Multiply the coefficients (7.5 and 2) and multiply the variables (a and x) together.

Result: 15ax

3. -0.6b * 4y: Multiply the coefficients (-0.6 and 4) and multiply the variables (b and y) together.

Result: -2.4by

Therefore, the simplified expressions are:

1. -6x * 1.25y = -7.5xy
2. 7.5a * 2x = 15ax
3. -0.6b * 4y = -2.4by
