Answer:
628 hope it helps
Step-by-step explanation:
Answer:
(4x+3)^2 = 18
16x+9=18
16x=9
<u>x=9/16</u>
Step-by-step explanation:
309 times 692 ***********************
The form (x - p)^2 = q is the form that completing the square will leave us with.
---Add 5 to both sides
x^2 - 8x = 5
---Divide the b term by 2, and square it. Then, add that number to both sides.
-8/2 = -4
(-4)^2 = 16
x^2 - 8x + 16 = 5 + 16
x^2 - 8x + 16 = 21
---Factor!
(x - 4)^2 = 21
p = 4
q = 21
Hope this helps!! :)
<span>Number of bowls left after 1 hour =
x - x/3 - 1/3 = 2x/3 - 1/3
</span><span> Number of bowls left after 2 hours = (2x/3 - 1/3) -
(2x/3 - 1/3)/2 - 1/2
= 2x/6 - 1/6 - 1/2
= 2x/6 - 4/6
= x/3 - 2/3
keep doing this untill u reach 0 bowls left
and then u'll get ur answer
