Answer:
9^2 = 81
12^2 = 144
63^= 3969
A^2 + B^2 = C^2
81 + 144 = 225
so these numbers do not make a right triangle
Answer:
Rhombus Square
Step-by-step explanation:
Answer:
the combination of numbers must then be:
9.7 + 8.6 which results to 18.3
9.6 + 8.7 yields 18.3 as well.

Answer: 6a^3-6a^2b+3ab-3b^2</h3>
=============================================
Work Shown:
(2a^2+b)(3a-3b)
c(3a-3b) ..... let c = 2a^2+b
3ac-3bc .... distribute
3a(c)-3b(c)
3a(2a^2+b)-3b(2a^2+b) .... plug in c = 2a^2+b
3a(2a^2)+3a(b)-3b(2a^2)-3b(b) ... distribute
6a^3+3ab-6a^2b-3b^2
6a^3-6a^2b+3ab-3b^2
You could also use the FOIL rule to get the same result. The box method is a visual way to keep track of the terms.
