Can a positive and negative number be equivalent

Yep.

Step-by-step explanation:

Negative numbers are under zero (see the number line for an increasingly complete clarification of this). Additionally, something contrary to any negative number is a positive number. ... The accompanying blended numbers are for the most part equivalent: - 1/6, - (1/6), (- 7)/6, 7/(- 6), and - 7/6.

Hope this helps!

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.

7

step-by-step explanation:

i'm assuming you need to figure out how many campers go into each tent.

i got the answer by:
