Answer:
d = -3
Step-by-step explanation:
Given the equation:
Solve for d:
Take both sides cube root we have;
![d =\sqrt[3]{-27}](https://tex.z-dn.net/?f=d%20%3D%5Csqrt%5B3%5D%7B-27%7D)
We can write 27 as:
then;
![d = \sqrt[3]{-3^3}](https://tex.z-dn.net/?f=d%20%3D%20%5Csqrt%5B3%5D%7B-3%5E3%7D)
Using the rules:
![\sqrt[n]{a^n} = a](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Ba%5En%7D%20%3D%20a)
![\sqrt[3]{-1} = -1](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B-1%7D%20%3D%20-1)
then;
![d = -\sqrt[3]{3^3} = -3](https://tex.z-dn.net/?f=d%20%3D%20-%5Csqrt%5B3%5D%7B3%5E3%7D%20%3D%20-3)
therefore, the unknown variable d is, -3
Number three is a parallelogram
Number four is a rhombus
The attributes of each quadrilateral is that it must have four sides
Number seven is true because if you fold a rectangle in half it will be congruent and rectangles always have at least one parallel side
Number eight is false because a square has all equal length sides and a rectangle does not have all equal sides making the two very different
HOPE THAT HELPS!!!!!!
I think 4/5 because if you multiply you get that!!!!!!
I think is D , hope i answer fast enough haha :D
