(6x^3/3x^4)^2 = (2/x)^2 = 4/x^2
2x - 6 = 20
2x = 20 + 6
2x = 26
x = 26/2
x = 13 <==
The area is found by base x height
To find the missing height in the first one you divide 147 by 15 3/4 and get 9 1/3.
To find the missing base in the second one you divide 140 5/8 by 11 1/4 and get 12 1/2.
To find the missing height in the third one you divide 151 3/16 by 10 1/4 and get 14 3/4.
Make me brainliest ! :)
