Write an equation and solve round to the nearest hundredth where necessary. 21 is 35% of what number

21 is 35% of 60.

35% * x = 21

Multiply both side by 100 and divide both sides by 35.

x = 21 * 100/35

21 * 100 = 2100

2100/35 = 60.

oml there it let me actually answer this time :)

Step-by-step explanation:

6 on both sides and twelve on the top and the bottom

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)
