Answer:
C. 60
Step-by-step explanation:
60+10=70
17 because 4 x 1.5 = 6, 50 / 1.5 = 33.33
5. The 5th figure will have 30 tiles.
6. The 6th figure will have 42 tiles.
7. The pattern is non-linear (quadratic).
8. The 20th figure can be made with 420 tiles.
_____
The Nth figure is made with n*(n+1) tiles. To answer question 8, you must solve
.. n(n +1) = 420
.. n^2 +n -420 = 0
.. (n +21)(n -20) = 0
.. n = 20 or -21 . . . . the negative solution is extraneous
Answer:
7
Step-by-step explanation:
2(3)(0) + 7
6(0) + 7
0 + 7
