x= 6
Step-by-step explanation:
ANSWER
Vertex form:

Vertex
V(-4,-11)
EXPLANATION
The given expression is

We complete the square to get the vertex form.
Add and subtract half the square of the coefficient of x.


The vertex is
V(-4,-11)
2.1+18.9
The answer is going to be 21 because 9+1=10, you then carry the 1 for 8 so it’s going to be 9+2 which equals to 11 now you carry the 1 to the 1 so it’ll be 2. Therefore it’s 21.0 or just cancel out the 0 and just leave it as 21.
Answer:
Okay, so a bit of math is involved, along with steps.
Step-by-step explanation:
Kyra invested $400 at 3% for 3 years. meaning 3% of $400 is 12. 400+12=
Year 1: $412
3% of 412=12.23+412=
Year 2: $424.23
3% of 424.23=12.7+423.23=
Year 3: $435.93
Kyra made $35.93 in investments.
Lishsawn invested $500 at 4% for 2 years. Meaning, 4% of $500 is 20. 500+20
Year 1: $520
4% of 520=20.8+520
Year 2: $540.8
Lishawn made $40.8 dollars in investments. Meaning that Lishawn made $4.87 more dollars
