Question

1)8×(-3+(-7)=?2)(-2)×(-5)-12​

Answer 1

Ответ:

1) 8*(-3+(-7)=-80

2)(-2)*(-5)-12=-2

Пошаговое объяснение:

1.1)(-3+(-7)=-3-7=-10

2)-10*8=80

2.1)(-2)*(-5)=10

2)10-12=-2

Answer 2

Let's solve these two expressions step by step:

1. $8 \times (-3 + (-7))$

First, we need to simplify the expression inside the parentheses:

$-3 + (-7) = -3 - 7 = -10$

Now, we can substitute this value back into the original expression:

$8 \times (-10) = -80$

So, the answer is -80.

2. $(-2) \times (-5) - 12$

First, let's multiply the numbers inside the parentheses:

$(-2) \times (-5) = 10$

Now, we can subtract 12 from this result:

$10 - 12 = -2$

So, the answer is -2.
