One cylinder has a volume that is 8 cm. less than g of the volume of a second cylinder. If the first cylinder's volume 216 cm, what is the correct equation and value of x, the volume of the second cylinder?
0 3x+8 = 216; x= 182cm
o *x-8-216; x= 196 cm
*x+8=216; x = 238 cm
o 3x-8= 216; x = 256cm

answer is 8x+24

area of vanessa's patio = length × width

given, length = (3x² + 5x + 10)

width = (x² - 3x - 1)

area of vanessa's patio = (3x² + 5x + 10)(x² - 3x - 1)

= 3x²(x² - 3x - 1) + 5x(x² - 3x - 1) + 10(x² - 3x - 1)

= 3x⁴ - 9x³ - 3x² + 5x³ - 15x² - 5x + 10x² - 30x - 10

= 3x⁴ - 4x³ - 8x² - 35x - 10

hence, expression of vanessa's patio = (3x⁴ - 4x³ - 8x² - 35x - 10)
