(3x − 2)(5x^2 − 7x + 2)

15^3−31^2+20−4

Step-by-step explanation:

Distribute

(3−2)(5^2−7+2)

3(5^2−7+2)−2(5^2−7+2)

Distribute

3(52−7+2)−2(5^2−7+2)

15^3−21^2+6−2(5^2−7x+2)

Distribute

15^3−21^2+6−2(5^2−7+2)

15^3−21^2+6−10^2+14−4

Combine like terms

15^3−21^2+6−10^2+14−4

15^3−31^2+6+14−4

Combine like terms

15^3−31^2+6+14−4

15^3−31^2+20−4

Solution

15^3−31^2+20−4

.24

step-by-step explanation:

the probability is   .24

the first player had the highest probability of getting a silver marble

the game could be made fair by adding back the marble that was drawn after each draw

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
