Answer:
The answer is A which is X^3 3 root y
It's an isosceles triangle because base angles are same( 45°).
area = width * length
or
A = W * L
55 = W * (W+6)
solve for width:
0 = W^2 + 6W - 55
this is a quadratic and has two solutions -11 and 5
a length can only be non-negative so discard -11.
width W = 5 miles
now the length is 5+6 = 11 miles
Answer:
R = 10 cm
Step-by-step explanation:
The area of a spherical shape is given by :

Where
r is the radius of the sphere
ATQ,
One large bubble separates into four small bubbles so that the total area of the small bubbles is equal to the area of the large bubble.
The radius of each small bubble is 5 cm
Using the given condition,

So, the radius of the large bubble is equal to 10 cm.
