would you like to know how I got that?
Its 11/12 , you need to divide the "wanted results" (every dog which is either black, with spots or both ) by every every possible result ( all dogs ). so 11/12=0.92
I’m pretty sure it’s 20 could be wrong
The answer is c because of Pythagorean’s theorem. a^2 + b^2 = c^2
So 5^2 + 12^2 = 13^2
25+144=169
From 2x^2 - 162,
factors would include 2(x+9)(x-9), in which x = 9,-9
