The equation that is equivalent to 15-7x=14 is x=7
15. A=7, 16. V=9, 17. D=26
512x3+192x2y+24xy2+y3512x
3+192x2 y+24xy2 +y3
Use the Pythagorean theorem to solve for x.
A^2 + B^2 = C^2
(50)^2 + (x)^2 = (60)^2
2500 + x^2 = 3600
x^2 = 3600 - 2500
x^2 = 1100
x = sqrt 1100
x = 33.17 yd
Round the answer to the nearest tenth
x = 33.2 yd
Answer: the water tower is 33.2 yd tall
