The half-life a particular radioactive substance is 6 seconds. If you started
with 50 grams of this substance, how
much of it would remain after 30
seconds?
First, complete the equation:
Remaining Amount = 50(1-0.55
Solve. Round your answer to the nearest hundredth.
Remaining Amount: [? ] grams

no not all of them.

step-by-step explanation:

some of them have a square base.

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)
