Question

3,2•(-7,12)+(-5,12)•3,2​

Answer 1

Ответ:

-39$\frac{21}{125}$

Пошаговое объяснение:

-3,2*7,12-5,12*3,2

3,2(-7,12-5,12)

3,2(-12,24)=-39$\frac{21}{125}$

Answer 2

To calculate the expression (3,2) • (-7,12) + (-5,12) • (3,2), you need to perform scalar multiplication and then add the results. Scalar multiplication involves multiplying each component of a vector by a scalar.

Let's break it down step by step:

1. Scalar multiplication: (3,2) • (-7,12) = (3 * -7, 2 * 12) = (-21, 24) (-5,12) • (3,2) = (-5 * 3, 12 * 2) = (-15, 24)

2. Addition of the results: (-21, 24) + (-15, 24) = (-21 - 15, 24 + 24) = (-36, 48)

So, the final result is (-36, 48).
