8.64E9 = 8640,000,000
8.64E14 = 864,000,000,000,000
8.64E11 = 864,000,000,000
8.64E13 = 86,400,000,000,000
<span>y+3=2(x-1)
a point or ordered pair (1, -3)
slope = 2
hope it helps</span>
So, an isosceles triangle has 2 equal sides, we will call them x.
The base can be modeled by 3+x
So, the perimeter is equal to x + 3+x + x
So
15.6 = 3x + 3
12.6 = 3x
4.2 = x
So, the lengths of the sides are 4.2, 4.2, 7.2
I am pretty sure it is A- The energy of a photon is h x c.
