Substitution z = tan(x), then you can write:
z^2 + 6z - 3
The absolute value of 10 is 10. The absolute value of 6 is six.
Sorry I don’t know that one but I recommend using the app photomath it really helps
BY ADDING BOTH THE EQUATIONS
7x+y=9
HOPE THIS WILL HELP U
Answer:
0.512a³ cubic units
Step-by-step explanation:
Given a cube of length, a, then when decreased by 20%, what's left is actually 80% of the original. So, for this case, we have a cube with a length of 80%(a) = 0.80a.
Now, to compute for the volume of a cube, we multiply the length three times to itself. Or, in other words, raise the length to the third power. That means the volume of the new cube is (0.8a)³ = 0.512a³ cubic units.
