Answer:
b=4, h=5
Step-by-step explanation:b(b+1) divided by 2 is 10, so b(b+1)=20 so b^2 + b =20 so b^2 +b -20=0 which equals (b+5)(b-4), giving us solutions -5 and 4. However, -5 is invalid bc it is negative, so base must be 4 making height 5
7^4 * 4^7

Answer:
13
Step-by-step explanation:
x² = 5²+12²
x² = 25+144
x² = 169
x² = 13²
x = 13
<u>2</u> <u>27</u>
3 times 1
<u>2 times 27 = 54</u>
3 times 1 = 3
54 divided by 3 = 18

Answer:
The equation of ellipse is

Step-by-step explanation:
The equation of an ellipse is

where(h,k) is the center and c is distance from the center to the foci is given by
. a is the distance from the center to the vertices and b is the distance from the center to the co-vertices.
The center of the ellipse is the mid-point of the vertices.
The mid point of the vertices
is
=
=(0,0)
a is the distance between the center and the vertices.
So, 

c is the distance between the center and the foci.
So, 
=5





The equation of ellipse is
