3x² (6x² - 13x - 5) =
3x² (2x - 5) (2x+1) .
Divide 305444 by 4
305444 / 4
76361
so
76361 times 4 is equal to 76361
the horizontal tangent line mean y'=0
8 - 2x = 0
x = 4
Answer:
The correct answer is C
Step-by-step explanation:
The height of the original triangle is 3 and the length is 6, so we have a ratio of 3:6. The only triangle that works is the one with a height of 5 and a length of 10 because both simplify to 1:2.
