Answer:

2x + 5 = l

Step-by-step explanation:

V = lwh

2x^3 + 17x^2 + 46x + 40 = l(x + 4)(x + 2)

2x^3 + 12x^2 + 16x + 5x^2 + 30x + 40 = l(x + 4)(x + 2)

2x(x^2) + 2x(6x) + 2x(8) + 5(x^2) + 5(6x) + 5(8) = l(x + 4)(x + 2)

2x(x^2 + 6x + 8) + 5(x^2 + 6x + 8) = l(x + 4)(x + 2)

(2x + 5)(x^2 + 6x + 8) = l(x + 4)(x + 2)

(2x + 5)(x^2 + 2x + 4x + 8) = l(x + 4)(x + 2)

(2x + 5)(x)(x) + x(2) + 4(x) + 4(2)) = l(x + 4)(x + 2)

(2x + 5)(x(x + 2) + 4(x + 2)) = l(x + 4)(x + 2)

(2x + 5)(x + 4) + 4(x + 2) = l(x + 4)(x + 2)

(x + 4)(x + 2) (x + 4)(x + 2)

2x + 5 = l

zlopas [31]

Answer:

Eric's expression is :

$20(\frac{1}{4})^w$

and Andrea's is :

$(1-0.5)^w$

In Eric's expression, 20 represents the initial amount of substance with which he has started the experiment. $\thinspace \frac{1}{4}\thinspace$ is the amount of substance left after each time period (in this case, each week).The variable w in this case represents the number of weeks.

Andrea's expression can be written as :

$1\cdot (1-0.5)^w$

The one outside of parentheses represents the initial amount of the substance. The one inside of parentheses represents 100% of the original amount of the substance. 0.5 represents the 50% of the substance that is lost each time period. The variable w in this case represents the number of weeks.
