The answer: d. < 1 and < 8
Answer:
the first step is wrong
it should be 4(x-4)/(x+1)(x-4) - (x+2)/(x-4)(x+1)
Answer: we need the table to solve this
Step-by-step explanation:
Answer:
x = 12
Step-by-step explanation:
In a right triangle (a triangle that has a ninety degree angle in it) the the square of the side opposite the right angle is always equal to the sum of the squares of the other two sides. Therefore, we can use the information we are given to figure out the missing side:
![15^2=225\\9^2=81\\225-81=144\\\sqrt[2]{144}=12](https://tex.z-dn.net/?f=15%5E2%3D225%5C%5C9%5E2%3D81%5C%5C225-81%3D144%5C%5C%5Csqrt%5B2%5D%7B144%7D%3D12)
Answer:
V=a^3
Step-by-step explanation:
The volume of a cube is found by multiplying the length, width, and height. A cube has the same length, width and height. In this case is it 9, so you multiply 9 by 9, three times, obtaining 729, which is your volume.
V=9^3
9x9x9
V=729
