9x + 4= 5x + 20 (alternate interior angles)
9x-5x =20-4
4x = 16
x= 16/4
x= 4
Explanation: 100 ➗10 = 10 ➗ 2 = 5 x 1.025 = 5.125.
789.35 ➗ 10 = 78.935 ➗ 2 = 39.4675 x 1.025
1) (3-x) x (3+x)
2) 5(5-x) x (5+x)
3) (3v-wy) x (3v+wy)
4) 2(k-m) x (k+m) x (k^2+m^2)
5) (ab-4c) x (ab+4c)

3.6 * 10^(-3) is the scientific notation
Wouldn't it be divided, I'm pretty sure it would be, if not I'm sorry
