and
Step-by-step explanation:
Given the expressions:
1)
2)
To find:
The expressions equivalent to the given expressions.
or the expressions which are not equivalent to any of the given expressions.
Solution:
First of all, let us solve the brackets from the given expressions.
can be written as
(because when we multiply a negative sign with negative, it becomes positive.)
Similarly can be written as
(because when we multiply a positive sign with negative, it becomes negative.)
Therefore, the answer is:

So, let's take a look! When doing volume, we always do (addition) and nothing else. The only time that we would have to multiply is if we would have to find the area, but in this case, we are (going to figure) out what would be the volume.
We would sum up the following:
.
I believe that we would multiply this by (2) because we would have to find the other side as well.
And this would give us . . . 64 as it's volume.
V= (64)

For the given triangle, x = 51°.
Step-by-step explanation:
Step 1:
In the given triangle, the angle is x°. The opposite side has a length of 7 units while the hypotenuse of the triangle measures 9 units. To calculate the value of x, we determine the sin of angle x where we divide the length of the opposite side by the length of the hypotenuse.
sin x°
Step 2:
The length of the opposite side = 7 units.
The length of the hypotenuse = 9 units.
So x° = 50.986°, rounding this off to the nearest degree we get x = 51°.
