Acylinder has a radius of 4x + 2 and a height of 5x + 4. which polynomial in standard form best describes the total volume of the cylinder? use the formula v = r²h for the colume of a cylinder.. a) 80x³ + 144x² + 84x + 16. b) 80x³ – 144x² + 84x + 16. c) 80x³ + 144x² + 84x – 16. d) 80x³ + 144x² – 84x + 16

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1

answer is 144
