Suppose the value R(d) of d dollars in euros is given by R(d)-d The cost P(n) in dollars to purchase and ship n purses is given

S_A_V [24]

<u>Corrected Question</u>

Suppose the value R(d) of d dollars in euros is given by $R(d)=\dfrac67 d$ . The cost in dollars to purchase and ship n purses is given by P(n)=66n+23. Write a formula for the cost, Q(n) in euros to purchase and ship n purses.

Answer:

$Q(n)=\dfrac67(66n+23)$

Step-by-step explanation:

The value R(d) of d dollars in euros is given by $R(d)=\dfrac67 d$

Therefore:

$R(1)=\dfrac67$

$T$hat is, 1 dollars =\dfrac67$ euros$

The cost P(n) in dollars to purchase and ship n purses is given by:

$P(n) = 66n+23.$

Therefore, the cost, Q(n) in euros to purchase and ship n purses

$=\dfrac67 \cdot P(n)\\Q(n)=\dfrac67(66n+23)$

Easy Question! Find the number that should be added to the expression to create a perfect square trinomial: x^2 − 8x

marysya [2.9K]

Answer: The answer is C

Step-by-step explanation:

Well, an example of a perfect square trinomial would look like is:

$a^2-2ab+b^2$ or $a^2+2ab+b^2$

So since we already know what $a^2$ is and what $2ab$ is we just have to find $b^2$

However, we would use the $a^2-2ab+b^2$ formula to solve this since we have a subtraction sign
