<h3>
Answer: x = (
y-2)^2 +
5</h3>
In other words, y-2 goes in the first box and 5 goes in the second box.
=================================================
Work Shown:
y^2 - 4y - x + 9 = 0
y^2 - 4y + 9 = x
x = y^2 - 4y + 9
x = y^2 - 4y + 4 + 5 .... rewrite 9 as 4+5
x = (y^2-4y+4) + 5
x = (y-2)^2 + 5 .... apply the perfect square factoring rule
So we'll have y-2 go in the first box and 5 goes in the second box
note: One version of the perfect square factoring rule says (a-b)^2 = a^2-2ab+b^2.
Answer:
$15 exact!!
Step-by-step explanation:
Have a good day!
4p = 2p + 3c....p = popcorn, c = candy bars
c = 6
4p = 2p + 3(6)
4p = 2p + 18
4p - 2p = 18
2p = 18
p = 18/2
p = 9......whoa....9 bucks for popcorn....nothing is cheap anymore
Answer: The required equation be
Step-by-step explanation:
Since we have given that
Let the number of meeting rooms a hotel has be m
Number of social chairs each meeting room has =325
So, total number of chairs m number of meeting rooms will have
Let the number of chairs be c
According to question, we get
Hence, the required equation be
