Select the procedure that can be used to show the converse of the Pythagorean theorem using side lengths chosen from 6 cm, 9 cm, 12 cm, and
15 cm.
A. Knowing that 62 + 122 + 152, draw the 6 cm side and the 12 cm
side with a right angle between them. The 15 cm side will fit to
form a right triangle.
B. Knowing that 92 + 122 = 152 draw the 9 cm side and the 12 cm
side with a right angle between them. The 15 cm side will fit to
form a right triangle.
C. Knowing that 62 +92 < 122, draw the 6 cm side and the 9 cm side
with a right angle between them. The 12 cm side will fit to form a
right triangle
D. Knowing that 92 + 122 = 152, draw any two of the sides with a right
angle between them. The third side will fit to form a right triangle.

Step-by-step explanation:

complete the steps to find the area of the trapezoid.

area of rectangle = 256   square units

area of triangle 1 = 24  square units

area of triangle 2 = 16  square units

area of triangle 3 =   96 square units

area of trapezoid = 120  square units

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
