Answer:
216 x^3 - 540 x^2 + 450 x - 125 = (6 x - 5)^3
Step-by-step explanation:
The first one cannot be a perfect cube, since the first term contains x^2 and not x^3.
the second one is not a perfect square (the coefficient of the middle term should be an even number: "-90")
The third expression is the perfect cube as shown.
Answer:
26 ft.
Step-by-step explanation:
1) First I would suggest swapping 8 and 2/3 from a mixed number into a fraction:
8 2/3=8+2/3=(24/3)+(2/3)=26/3
2) Next you just need to multiply the number of shelves John wants to make by the required amount of lumber. He wants to make 3 shelves and each one requires 8 2/3 ft. of lumber, which(as we found above) is 26/3 ft. of lumber:
3×(26/3)=26
So John will need 26 ft. of lumber for his shelving.
Answer:
I believe the answer is transative property. I'm currently taking the test so I'm not 100% sure if I'm right yet.
Step-by-step explanation:
In step one, AGE and HGB are verticle angles since they are opposite of each other. then step two is alternate interior angles because they are interior angles opposite of each other, self-explanatory. the reason I choose the transitive property over the corresponding angles theorem is because the transitive property states: among A B and C, if A=B and B=c then A=C and in this case since AGE=HGB andHGB=CHE then AGE=CHE. I hope this helps and if you know the right answer just put it in the comments, if I'm wrong ofc.
