Let x is the side of the square
so A = x * x or A = x^2 = 36
As you know 36 is a perfect square root = 6^2
Then  x = 6 cm

Perimeter = 4x = 4(6) = 24 cm

Describe a real life scenario where inequalities are used and state the inequality
Hunter-Best [27]
AS North Korea is generally closed off the foreigners, the Nato nations & others can only guess how much nukes the NK have. Due to reports of missiles flying & landing in water, we can interpret that they have more than 1 missile. However, we believe that they have less than 100 still

1 < x < 100

this means that x is greater than 1, yet less than 100. 

hope this helps

Solve the inequality.
pogonyaev

Answer:

q > 5/6

Step-by-step explanation:

The LCD is (2)(3) = 6.  Mult. all three terms by 6, we get:

6q - 3 > 2.  Isolate q by adding 3 to both sides:

6q > 5.  Then q > 5/6 (the third possible answer).

Write the equation for a parabola with a focus at (-2,5) and a directrix at y=3.
Fofino [41]

Answer:

(x+2)²=4(y-4)

or y=1/4 (x+2)²+4

Step-by-step explanation:

directrix y=3 and focus (-2,5) to find te equation of parabola we use the equation :

(x-h)²=4p(y-k)

vertex(h,k) : the vertex is half way between the focus and the directrix

y(vertex)=y(focus)+directrix/2

y=5+3/2 ⇒8/2=4

x is the same as the c of the focus =-2

vertex (-2,4)

to find the distance (p) which is the distance between the vertex and focus

p=5-4=1

substitute h=(-2), k=(4) and p=(1) in the equation : (x-h)²=4p(y-k)

(x-(-2)²=4(1)(y-4)

(x+2)²=4(y-4)
