Answer: Two solutions
Step-by-step explanation:
1. x =(-2-√-76)/-8=(1+i√ 19 )/4= 0.2500-1.0897i
2. x =(-2+√-76)/-8=(1-i√ 19 )/4= 0.2500+1.0897i
Answer:
Elimination
Step-by-step explanation:
You would not do substitution since it would not work so you do elimination since the 4y and -4y eliminate then you just solve for it.
Answer:4th answer
Step-by-step explanation:
if width=w
Length =2w+1
Area =length *breadth
36=w(2w+1)
36=2w^2+w
0=2w^2+w-36
