Answer:
Step-by-step explanation:
There is really no way to show that of I know of without drawing it but here is this. I hope this helps and not really exact on position but that is very close.
Answer:
there's a lot:
Step-by-step explanation:
4/6,3/9,4/12,5/15,10/30,20/60,60/180.
this is the most i can do until i cant multiply anymore.
The answer would prob around $188.70 because .85x102=86.7 so add that to 102 and u get 188.70 but I'm prob wrong and I have a test on this tomorrow

25a⁴ - 10a²z² - 8z⁴ <em>multiply 25*-8 = -200 to find factors (10*-20 = 200), (10 - 20 = -10)</em>
25a⁴ + 10a²z² - 20a²z² - 8z⁴ <em>factor the left two and right two terms</em>
5a²(5a² + 2z²) -4z²(5a² + 2z²) <em>one factor from each side should be identical</em>
= (5a² - 4z²)(5a² + 2z²)
