A trapezoid was broken into a rectangle and a triangle. What is the length, b, of the base of the triangle? O 2 cm
O 4 cm
O 6 cm
O 8 cm​

2

Step-by-step explanation:

because if 10 is the whole line of the base at the bottom of the trapezoid

and 8 is the whole top 10-8=2

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
