Which expression has the same value as –18+(-9)?
0 -18/2
0-12/(-3)
0-10/5
O -8/(-4)

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.

answer: 1) twenty-seven times y

              2) twenty-seven multiplied by y
