For x²+bx+c, to complete the square, you add (half of b)²
b=8 in this case, so you add 4², which is 16
x²+8x+16-16-4
y=(x+4)²-20 is the final form.
Answer:
80%
Step-by-step explanation:
75% + 20% - 15% = 80%
The probability is 80%
Quantity of paint left = 
gallons
Solution:
Quantity of yellow paint = 
gallons
Quantity of green paint = 
gallons
Quantity of blue paint = 
gallons
Quantity of paint used = 
gallons of each paint
Quantity of paint left = 
gallons of each paint
Quantity of paint left = 
Taking LCM for 5, 6, 8, we get LCM = 120
Hence, Mark will have gallons of paint left after painting the mural.
You have to do 1= -4+x divided by 2 and then 5= 2+y divided by 2... this is how you find the missing coordinate since your given the other coordinate and the midpoint... I am learning the same thing in geometry right now ahah glad I can help
The arc is 4 right,
And the whole circle has a perimeter of 20.
If you do 20/4, you get a total of 5 of those pink arcs that fit in the circle.
A circle has 360 degrees, so if you do 360/5 = 72 and That’s your answer. I hope you understand my logic, if you don’t I can clear some things up....?
ANSWER:
72 degrees
