The answer should be B. you combine the like terms. when it is a negative sign in front of the parenthesis, when removing the parenthesis, every term inside the parenthesis need to change sign, negative to positive, positive to negative.
Expand brackets first which would be 13 + - 12 - - 5*. So this would be 13- 12 + 5 = 6
*+5 because 2 negatives make a positive
8(4k - 4) = -5k - 32
32k - 32 = -5k -32
32k + 5k = -32 + 32
37k = 0
k= 0/37
k= 0
Answer:
It simply is the product between 8 and 1.8 so 14.4, as anything added to himself n times is equal to the product between the number and n.
In fractions:
1.8 = 18/10 = 9/5
8·(9/5) = 72/5
