8 / 9 = 0.8888888888888888888888888889...
So it is a repeating decimal
Let's solve this problem step-by-step.
STEP-BY-STEP SOLUTION:
First let's establish that the problem requires the border to be as long as the total perimeter of the rectangular bulletin board.
Therefore:
Total length of border = Perimeter of rectangular bulletin board
As a rectangle has a total of four sides with two equivalent longer sides and two equivalent shorter sides, we must multiply the value of each of the two sides by two.
Total length of border = 2 ( 2 ) + 2 ( 4 )
Total length of border = 4 + 8
Total length of border = 12 feet
12 > 10
ANSWER:
Therefore, 10 feet of border isn't enough.

0.075(22 + 1.25s) = 1.65 +0.09375s
= 1.65 + 0.09s (round to the nearest hundredth)
Answer:
9.5
Step-by-step explanation:
Add all the sides together
f(x) = (x - 
)² - 
the equation of a quadratic in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
given a quadratic in standard form : y = ax² + bx + c ( a ≠ 0 )
then the x- coordinate of the vertex is
= - 
f(x) = x² - 11x + 9 is in standard form
with a = 1, b = - 11 and c = 9
= - 
=
substitute this value into the equation for y- coordinate
y = ()² - 11() + 9
= 
- 
+ 
= -
f(x) = (x - )² - ← in vertex form
