Simplify by combining like terms step by step
- (3x - 4y) + x

solve each formula for the indicated variable. step by step
h = vt -5t^2 , for v

there is no image attacted

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.
