➷  Split it into different sections and calculate the area:

4 x 2 = 8

3 x 2 = 5

4 x 2 = 8

Add these together:

8 + 8 + 5  = 21 (whatever unit it is)^2

step-by-step explanation:

time of 9 192 631 770 periods of the radiation corresponding to the transition between the 2 hyperfine levels of the ground state of the caesium 133 atom at 0 k (but other seconds are sometimes used in astronomy)

-8/2y-8=5/y+4-7y+8/y^2-16

we move all terms to the left:

-8/2y-8-(5/y+4-7y+8/y^2-16)=0

we can not solve this equation
