If I negate a certain number, n, 905 times, I get -65. If I negate n 908 times, what number would I get? Recall that negating a number x means replacing it with -x.

i think it is 70

step-by-step explanation:

x/3-10=8

x/3=18

x=48

the volume is the product of the area of the base, 3x(3x+4), and the height, 3x-1

step-by-step explanation:

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)
