Question

-8,5а•(-2b)=? Допоможіть будь ласка

Answer 1

Ответ:

-8,5а*(-2b)=17ab

При умножение отрицательных чисел всегда получится положительное, так как при умножении минуса на минус всегда будет плюс

Answer 2

$-8,5a*(-2b)=8,5a*(2b)=17ab$

Answer 3

To solve the equation -8.5a * (-2b), we can use the distributive property of multiplication over addition.

The distributive property states that for any real numbers a, b, and c, the product of a and the sum of b and c is equal to the sum of the products of a and b, and a and c. In other words, a * (b + c) = a * b + a * c.

In this case, we have -8.5a * (-2b). Using the distributive property, we can rewrite this as (-8.5a) * (-2b) = (-8.5a) * (-2) * b.

Multiplying -8.5a by -2 gives us 17a, so the equation simplifies to 17a * b.

Therefore, the solution to the equation -8.5a * (-2b) is 17a * b.
