Wes is 4 years older than his sister. Let x be his sister's age. Write an expression that tells how old Wes is.

x+4

if x is Wes' sister's age, then it would be x + 4 since Wes is 4 years older.

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.
