Answer:
16s^2 -9
Step-by-step explanation:
(4s+3)(4s–3)
FOIL
first : 4x*4x = 16s^2
outer -3 *4s = -12s
inner 3*4s = 12s
last = 3* -3 = -9
Add them together
16s^2 -12s+12s -9
Combine like terms
16s^2 -9
Answer:
A,D
Step-by-step explanation:
The missing exponent is 2
All of the answers you put are correct. good job!
The Answer is A
Explanation:
The standard form equation for an ellipse is:
(x - h)² / a² + (y - k)² / b² = 1
So looking at the picture above you can see that the center of the ellipse is at the origin which is (0;0) making both h and k zero.
It is then observed that the x-intercepts are at 12 meaning a=12 and y- intercepts are at approximately square root of 95 which is 9.746... which are 'k'
So you can conclude by saying that:
x²/12² + y²/(sqrt of 95)² = 1
then giving you the answer of A which is:
x²/144 + y²/95 = 1
