(1.2 x 10^13) - (4 x 10^11)

the answer is 11,600,000,000,000

Step-by-step explanation:

pemdas

(1.2 x 10 ^13) - (4 x 10 ^11)

10^13 = 10,000,000,000,000 put that in scientific notation to make it simpler do same for 10 ^11

10 x 10^13

(1.2 x 10 x 10^13) - ( 4 x 10 x 10^11)

now solve the first equasion

12,000,000,000,000 - 400,000,000,000

subtract

11,600,000,000,000

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
