Challenge a scientist is growing bacteria in three colonies, a, b, and c. at the moment, there are 2.3 times 10 superscript 5 baseline bacteria in colony a, 1.2 times 10 superscript 5 baseline bacteria in colony b, and 6.6 times 10 superscript 5 baseline bacteria in all. express each of these numbers in standard form. then use those results to find the number of bacteria in colony c by evaluating the expression shown below .6.6 times 10 superscript 5 baseline minus left parenthesis 2.3 times 10 superscript 5 baseline plus 1.2 times 10 superscript 5 right parenthesis 2.3 times 10 superscript 5 equals nothing

.

step-by-step explanation:

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

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)

35/2 is it i think maybe
