Answer:
3(x + 4) = 3(x) + 3(4)
3(x + 4) = 3x + 12
3x + 12 = 3x + 12
Subtract 12 from both sides
3x + 12 - 12 = 3x + 12 - 12
3x = 3x
3x - 3x = 3x - 3x
= 0
Answer: It's Already simplified!
Answer:5
Step-by-step explanation:
3(5)+2=17
5(5)-8=17
X=5
The discriminate formula is b^2+4ac so -5^2+4(1)(6)=49
