Bry blew 91 bubbles. Ken blew 7 bubbles.

How many times as many bubbles did Bry blow?

Bry blew 13 times as many bubbles as Ken.

Step-by-step explanation:

because 91/7=13

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.
