If B=2t+10B=2t+10 and C=-t^{2}-t-1,C=−t 2 −t−1, find an expression that equals 3B-3C3B−3C in standard form.

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.

c - they will have the same distribution

step-by-step explanation:

this is the only one that could make sense. : )
