Step-by-step explanation:
<h3>to understand this</h3><h3>you need to know about:</h3>
<h3>let's solve:</h3>
parimeter of a square:4a
according to the question
divide both sides by 4:
cancel 2 from both sides:
divide both sides by 8
Answer:
(x-2) and second slot is (x+7)
Second Answer= (x-2) and second slot is (x-8)
To start you need to find out how many shirts are made a day. if 6/1200=9/x so then x= 1800 shirts made a day. to make 12600 shirts you will divide 12600 by 1800 = 7days
Y=3x²-6x+4
to put in vertex form, make a square by adding (half of b)²
but first, we have to make a=1 by take out the 3:
y=3(x²-2x)+4
b=-2, half of b=-1, (-1)²=1, so add 1, then subtract 1 inside the parenthesis:
y=3(x²-2x+1-1)+4
make the square: y=3[(x-1)²-1]+4
simplify: y=3(x-1)²-3+4=3(x-1)²+1
so the answer is A.
