Approximately how many liters are in 20 gallons 1 L 0.26 gal.

77 litres

Step-by-step explanation:

1L = 0.26 gal

0.26 gal = 1L

Divide both sides by 0.26

1 gal = 1 ➗ 0.26

1 gal = 3.85 L

Now multiply both sides by 20

20 gal = 3.85 × 20

20 gallons = 77 litres

8x-7x> 14-8

x> 6

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)
