Answer:
35+28=63
Step-by-step explanation:
hope this helps
The area would be 63.The steps to how I got that anwser:
1.] Write your formula
A=bh
----
2
2.]Begin by plugging in your measurements
A=7.5 times 16.8
-------------------
2
3.]Multiply the top two numbers together
A=126
-----
2
4.]Divide to get your final anwser
A=63
Answer:
Step-by-step explanation:
An ellipse centered a point (h,k) has the following formula:
The distance between foci is:
![2\cdot c = \sqrt{[8-(-8)]^{2}+(0-0)^{2}}](https://tex.z-dn.net/?f=2%5Ccdot%20c%20%3D%20%5Csqrt%7B%5B8-%28-8%29%5D%5E%7B2%7D%2B%280-0%29%5E%7B2%7D%7D)
The center of the ellipse is:
The known vertex is on the horizontal axis of the ellipse. Then, the length of the semi-major axis is:
The length of the semi-minor axis is given by the following expression:
The equation of the ellipse is:
Answer:
See explanation.
Step-by-step explanation:
First put 2x-4 equal to 0 and solve it.
2x-4=0
2x=4
x=2
Now plug 2 into the polynomial and see if it equals to 0
In case it's not, then it is not a factor of it
2(2)^5 - 4(2)^4 + 2x^2 -2(2) - 4 = 0
So it's indeed a factor of the polynomial.
Hope this helps!
