Which set of shapes contains members that are always similar to one another? trapezoids isosceles triangles equilateral triangles rectangles pentagons

Equilateral triangles.

Step-by-step explanation:

We know that in similar polygons, its all the corresponding angles are congruent.

Only the set of equilateral triangles contains members that are always similar( by AAA similarity criteria ) to one another as the measure of all the angles of equilateral triangle is fixed i.e. 60°.

Rest other do not have fixed measure for angles in it.

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8
