Ross drives 256 miles in 4 hours. If Ross continues to drive at the same rate, how many miles can he drive in 12 hours?

768

Step-by-step explanation:

4 x 3 = 12

so 256 x 3 = 768

is this a multiple choice question?

if so it's a and c

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.
