Answer: 9x - 1 = 9(2) - 1 = 17

Step-by-step explanation:

m∠ABD = m∠ABC + m∠CBD

87 = 9x -1 + 6x + 58

87 = 15x + 57

30 = 15x

2 = x

A geometric pattern is a pattern made out of geometric forms that are generally repeated, much like a wallpaper design.

The given figure shows that one pattern consists of one box formed from the 4 sticks.

Pattrern 1 = 1 box  

Pattern 2 = 2 box

Pattern 6 = 6 box

1 box = 4 stick

Pattern 6 = 6 box = 6 ×4 = 24 sticks

ruslelena [56]

Answer:

(a) 65536 - the basic principle of counting

(b) 2520 - use the multinomials.  

Step-by-step explanation:

Divide 8 people among 4 schools

The teachers are different among themselves, and so are the schools.  

(a)

Every teacher can choose a school. By the basic principle of counting: 4.4.4.4.4.4.4.4 = 4^8 = 65536

different divisions of the teachers

Note: this does not ensure that every school gets a teacher  

(b) - <u>Every school gets precisely 2 teachers:</u>

to divide 8 different objects into four groups of fixed sizes 2, 2, 2 and 2, use the multinomial coefficient  

( 8   2, 2, 2, 2) = (8!)/(2!2!2!2!) ==> 2520

different divisions of the teachers
