7) Express the number in scientific notation: 0.0021354 A. 21.35 x 10^-4
B. 0.2135 x 10^-2
C. 213.5 x 10^-5
D. 2.135 x 10^-3

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2

step-by-step explanation:

a'(12.5,11.25)

slope=(y1-y2)/(x1-x2)
