C
given x² + 16x = 41
to complete the square on this equation
since the coefficient of the x² term is 1
add (half the coefficient of the x-term )² to both sides
x² + 2(8)x + 64 = 41+ 64
(x + 8 )² = 105 → C
On this equation this formula implies: (a2-b2)=(a+b)(a-b)
so the factored form of equation a2-121 will be:
(a+11)(a-11)
hope that helps :)
A = s^2 and P = 4s.
So if A = 25, then s^2 = 25 so s = 5. Then 4*s = 4*5 = 20
The perimeter of a square with an area of 25cm^2 is 20cm.
Increase the perimeter by 4 to get 24cm. Then 4s = 24 implies s = 6. Then s^2 = A = 6^2 = 36.
Now the area is 36 cm^2
