Two petri dishes were on the desktop in dr. mcfarlan's lab.
dish a had cells with a radius of 4.1 x 10-15 cm. dish b had cells that had a radius of 2.3 x 10-13 cm. what is the sum of the radii of
the two types of cells, using scientific notation?
a.2.341 x 10-17 cm
b. 23.41 x 10-16 cm
c. 234.1 * 10-15 cm
d. 2.341 x 10-13 cm

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)
