Answer:
B I think
Step-by-step explanation:
Answer:
1. 10n
2. 3x^2z^2
3. 2(9n^3 - 3n^2 + 3n - 1)
4. (Put the same thing)
5. There are no common factors so it is completely factored out.
Step-by-step explanation:
For 1, you gotta find the gcf of the numbers and the variables. So, the common factor of 90, 70, 70, and -80 is 10. Nothing else greater than 10 divides these numbers. For the variables, only "n" is the GCF, as there is one "n" and all the other numbers have n^2 and etc.
For 2, same thing, you have to find the gcf for the numbers and the variables.
3. same thing ;-; (gcf is 2 btw, nothing divides the variables because 2 has no "n".
4. theres nothing that divides the numbers or the variables. So, the gcf is just 1.
The answer to this problem is nine.
Answer: 57.8512 feet (approx)
Step-by-step explanation:
Let h be the height of the stone face.
The angle of elevation from one sight to the bottom of face that is 750 feet far from the base of the mountain is 33°
⇒ The distance of the base of the stone face from the base of the mountain = 
The angle of elevation from another sight to the top of face is 36° that is also 750 feet away from the base of the mountain,
Therefore,
The distance of the top of the stone face from the base of the mountain = (h + 487.055694898) feet
By the trigonometry,



Therefore, the height of the stone face is 57.8512 feet (approx).
