Complete the square
since a=1 for ax²+bx²+c=0
we can do
take 1/2 of the linear coefient and square it
-6/2=-3, (-3)²=9
add that to both sides
x²-3x+9-25=9
factor perfect square trinomial
(x-3)²-25=9
add 25 to both sides
(x-3)²=34
sqrt both sides, rmember to take positive and negative roots
x-3=+/-√34
add 3
x=3+/-√34
x=3+√34 or 3-√34
Answer:
True
Step-by-step explanation:
because is it asking that the hight (y) is in what place in a more spicific wording
I am pretty sure that the answer is 15+ n or it could be 15n
===> Mr. Jackson bought / . of beef:
===> He cooked / of it for lunch:
Solution ===> Mr Jackson, had 2 / 5 Lbs. left
===>
If he cooked / of it for lunch:
===> Mr Jackson, had
/ of the original amount left.
===> Since ( / )( / )
===> / * /
===> /
Mr Jackson, had
/
.
left.
write the answer as one expression; Then Solve:
(
/ )( −
/ )
8 / 5 ( 1 - 3 / 4 )
= 8 / 5 ( 1 / 4 )
= 2 / 5 ( Decimal: 2 / 5 ====> 0.4 )
Answer, 2 / 5 Lbs.; of beef, Mr Jackson, Had left.
