What is 3x10^7 x 8x10^4 in standard form

They are already in standard form.

Step-by-step explanation:

dilation scale factor 2: starting with δabc, draw the dilation image of the triangle with a center at the origin and a scale factor of two. notice that every coordinate of the original triangle has been multiplied by the scale factor (x2). dilation with scale factor 2, multiply by 2.

x = 3 ± √(5+y)
