Answer:
1. B and C
2. -10x-15
Step-by-step explanation:
QUESTION 1
Lets substitute x for 1.
4-1=3 (Original)
A: 1-4=-3 (NOT Equivalent)
B: 4+-1=3 (Equal)
C: -1+4=3 (Equal)
D: -4+1=-3 (NOT Equivalent)
E: 4+1= 5 (NOT Equivalent)
Question 1 would be B and C.
QUESTION 2
The distributive property of multiplication over addition is applied when you multiply a value by a sum.
Lets get rid of the parenthesis by multiplying it.
5(-2x-3) = -10x-15
5 × -2x -10x
5 × -3 = -15
