How do I use the distributive property to solve 6m(m+3n+1) and -2x(3y+9)

Plots and patterns may vary. As the number of pennies ... 12y – 5y = -21 5(-2n + 1) + 3n ... Sample I would isolate m in the second equation

Step-by-step explanation:

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.
