Answer:
In math, prime numbers are whole numbers greater than 1, which have only two factors – 1 and the number itself. Prime numbers are divisible only by the number 1 or itself. For example, 2, 3, 5, 7, and 11 are the first few prime numbers.

Step-by-step explanation:
The formula for the area of a square is:
A
=
s
2
Where:
A
is the area of the square.
s
is the length of the side of a square.
Substituting and solving for
s
gives:
225
cm
2
=
s

The formula for the perimeter of a square is:
p
=
4
s
Where:
p
is the perimeter of the square.
s
is the length of the side of a square.
Substituting for

The correct answer is choice d because you would divide x by 2 to get 70. then you do the same with y so 35/2 = 17.5
Answer:
Step-by-step explanation:
1) x² + 6x + 11 = 0
a = coefficient of x² = 1
b = coefficient of x = 6
c = Constant = 11
Roots = (-b ± √b² - 4ac)/2a
Roots = 
2) 2x² - 16x = 50
Divide the whole equation by 2
x² - 8x = 25
Divide the coefficient of x (i. e 8 ) by 2 = 8/2 = 4, Now add 4 to both sides of the equation
x² - 8x + 4 = 25 + 4
x² - 2*4*x + 2² = 29
(x - 2)² = 29
Take square root both side
