Question

Спростіть вирази a) -2x×(-3y)b) -4(x-2)c) (3x-1)×2​

Answer 1

Ответ:

1.) -2х×(-3у)=6ху

2.) -4(х-2)=-4х+8

3.) (3х-1)×2=6х-2

Answer 2

a) -2x × (-3y)

When multiplying two negative numbers, the result is positive. So, we can simplify the expression as follows:

-2x × (-3y) = 2x × 3y = 6xy

Therefore, the simplified expression is 6xy.

b) -4(x - 2)

To simplify this expression, we need to distribute the -4 to both terms inside the parentheses:

-4(x - 2) = -4x + 8

So, the simplified expression is -4x + 8.

c) (3x - 1) × 2

To simplify this expression, we need to distribute the 2 to both terms inside the parentheses:

(3x - 1) × 2 = 6x - 2

Therefore, the simplified expression is 6x - 2.
