Maya is mailing packages. each small package costs her $2.90 to send . each larded package costs her $4.50. how much will it cost her to send 6 small packages and 4 large packages

$35.40

Step-by-step explanation:

1. $4.50 multiplied by 4 is $18

2. $2.90 multiplied by 6 is $17.4

3. $18+$17.4=$35.40

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.
