Al usar la propiedad distributiva si el termino que esta afuera de los parentesis es negativo entonces el signo de cada uno de los terminos que estan dentro de los parentesis cambiara. Si es verdadero falso o a veces y explicación

It's true

Step-by-step explanation:

The distributive property is that by which the multiplication of a number by a sum will give us the same as the sum of each of the addends multiplied by that number. If the term outside is negative, the sign of each of the numbers inside the parentheses changes, for example:

-1 x (3 + 4) = 1 x (-3-4) = -7

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24
