Answer:
C. 25/6 ft²
Step-by-step explanation:
Let's call the dimensions of Rectangle B x and y. Then ...
xy = 5 ft²
and
x² = 6 ft²
We want to find the value of y². Solving the first equation for y, then substituting for x², we have ...
y = (5 ft²)/x
y² = ((5 ft²)/x) = 25 ft⁴/x² = 25 ft⁴/(6 ft²)
y² = (25/6) ft² . . . . . . . matches choice C

10
Step-by-step explanation:
Step-by-step explanation:
I'm not sure if the question is 
or 
, so we can do both:
First, let's subtract 
from both sides to isolate the 
on the left-hand side:
Next, let's multiply both sides by to get by itself:
First, let's subtract from both sides to isolate the on the left-hand side:
Next, we can take the reciprocal of both sides to get rid of the fraction on the side with :
Next, we can divide both sides by to get by itself:
