This is an ellipse.
Equation of an ellipse: 
Let's find the center point first. We can do this by finding out the midpoint between the vertices or the foci.
(-9+7)/2=-1
Center: (-1,3)
Now we need to find a and b (length along x and length along y).
We know "a". It is the distance between the center and the right or left bound.
a=7-(-1)=8
To find out "b", first see that...
b^2=a^2-(distance from center to foci)^2
foci distance=3-(-1)=4
b^2=8^2-4^2
b^2=64-16
b^2=48
b=4√3
answer: 
Answer:
The expression for the given value of the variable d=75 is, 135
Step-by-step explanation:
Given the expression:
![2d+\sqrt[3]{-45d}](https://tex.z-dn.net/?f=2d%2B%5Csqrt%5B3%5D%7B-45d%7D)
....[1]
We have to find the value for the given expression when d = 75
Substitute the value of d in [1] we have
![2(75)+\sqrt[3]{-45(75)}](https://tex.z-dn.net/?f=2%2875%29%2B%5Csqrt%5B3%5D%7B-45%2875%29%7D)
⇒ ![150+\sqrt[3]{-3375}](https://tex.z-dn.net/?f=150%2B%5Csqrt%5B3%5D%7B-3375%7D)
⇒
Simplify:
⇒
Therefore, the expression for the given value of the variable d=75 is, 135
