Keith wrote the expression shown to determine the cost in dollars for an upcoming trip. (127.50 - 23.50) + 3(86.50 + 4) Which expression is equivalent to the one Keith wrote?

104 + 3(90.50)

Step-by-step explanation:

Given the cost expression :

(127.50 - 23.50) + 3(86.50 + 4)

Equivalent expression :

(127.50 - 23.50) + 3(86.50 + 4)

104 + 3(90.50)

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.
