-21x^3 - 8x^3 = -29x^3
-7/4x^(1/2) - 0 = -7/4x^(1/2)
-6x^(1/4)
-12x^(-1/2)
12x^(-1/4)
14x^4
Therefore, the correct option is the 2nd one.
Answer:

Step-by-step explanation:
To find
of the volume, we first must know the total volume.
The formula to find volume:

We know the length is 25m, we know the width is 20m and we know the depth is 5m.
So, we can substitute them into the equation:

Now we know the total volume, we can find out the volume when it is
full:

Therefore, our final answer is
.
The gcf of 18 and 42<span> is the largest positive integer that divides the numbers </span>18 and 42<span> without a remainder. Spelled out, it is the </span>greatest common factor of 18 and 42<span>. Here you can find the </span>gcf of 18 and 42<span>, along with a total of three methods for computing it.</span>
It would be 6.875 i do believe
123 is a linear pair with the inside angle so
180-124= 57. Now we have two inside angles and a triangle has to be 180 degrees so
57+42=99 we know that both angles equals 99 so
180-99=80. The third angle is 81 and is a linear pair with x soooo
180-81=99
X is equal to 99. You can also do corresponding angles and have X be 99 because of the inside angle that’s also 99
