Answer:
12x + 18y + 6z + 4x - 4z
Step-by-step explanation:
Given the expression : 3(4x + 6y + 2z) + 4(x – z)
To eliminate the parenthesis ; we use the distributive property :
3(4x + 6y + 2z) + 4(x – z) becomes ;
3*4x + 3*6y + 3*2z + 4*x + 4*-z
12x + 18y + 6z + 4x - 4z
Hence,
12x + 4x + 18y + 6z - 4z
16x + 18y + 2z
? You do 5+2= 7
Is that what you are asking
3/2 is an improper fraction, where the denominator (bottom number) is smaller than the top (numerator)
1 1/2 is this same fraction but now it is not improper.
The answer is D , Yes they are parallel because the slopes are equal
