What is 6a+6=-18
a=___

a=-4

Step-by-step explanation:

   6a+6=-18

         -6   -6

   6a=-24

  ___  ___

   6        6

a=-4

a=-4

Step-by-step explanation:

Subtract

from both sides of the equation

6+6=−18

6+6−6=−18−6

Simplify

Subtract the numbers

Subtract the numbers

6=−24

Divide both sides of the equation by the same term

6=−24

66=−246

Simplify

Cancel terms that are in both the numerator and denominator

Divide the numbers

=−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.
