Answer: B)subtract 5
(x-5)^2-25
Step-by-step explanation:
2a=-10
Divide both sides by 2
2a/2=-10/2
Simplify
a=-5
Add and subtract
x^2-10x+(-5)^2-(-5)^2
Complete the square
(x-5)^2-(-5)^2
Simplify;
(x-5)^2-25

Answer: 55 miles per hour
Step-by-step explanation:
Here is the complete question:
Seth's family plans to drive 220 miles to their vacation spot. They would like to complete the drive in 4 hours.
Find the average speed in miles per hour needed to make the trip in the desired.
From the question, Seth's family plans to drive 220 miles to their vacation spot and they would like to complete the drive in 4 hours.
Average speed is calculated as distance travelled divided by the time taken. This will be:
Speed = Distance/Time
Average speed = 220/4
Average speed = 55 miles per hour

Let's simplify step-by-step.
p+6pq−2pq−129
=p+6pq+−2pq+−129
Combine Like Terms:
=p+6pq+−2pq+−129
=(6pq+−2pq)+(p)+(−129)
=4pq+p+−129
Answer:
=4pq+p−129

Let's simplify step-by-step.
2x−3y+b(3y−2x)+2.718282−(2x−3y)
Distribute the Negative Sign:
=2x−3y+b(3y−2x)+2.718282+−1(2x−3y)
=2x+−3y+b(3y−2x)+2.718282+−1(2x)+−1(−3y)
=2x+−3y+b(3y−2x)+2.718282+−2x+3y
Distribute:
=2x+−3y+(b)(3y)+(b)(−2x)+2.718282+−2x+3y
=2x+−3y+3by+−2bx+2.718282+−2x+3y
Combine Like Terms:
=2x+−3y+3by+−2bx+2.718282+−2x+3y
=(−2bx)+(3by)+(2x+−2x)+(−3y+3y)+(2.718282)
=−2bx+3by+2.718282
Answer:
=−2bx+3by+2.718282
No, 11/5 simplified is 2 1/5 so it is in between 2 and 3
