Answer:
Step-by-step explanation:
Pythagorean theorem is:
1 → B
multiply each term in the parenthesis by the 6 outside
6(b-7) = 6b - 42
2 → D
multiply each term in the parenthesis by the 3 outside
3(4x+6y+2) = 12x+18y+6
3 → A
the value outside the parenthesis is -1, hence each term inside is multiplied by -1
-1(6x+5y) = -6x -5y
It looks like the measure would be 97 or 93 I think
Just multiply the tops together and the bottoms together :)
What three? there is no picture
