Last year, the price per transaction of certain company increases p percent from the year before, and the number of transactions increase n percent from the year before. total revenue is simply the number of transactions times the price per transaction. assume this one transaction is this company's only source of revenue. which of the following is the percent increase in revenue last year, from the year before?
a. p∗np∗n %
b. (p+n)(p+n)
c. (p+n+(p+n+p∗n100)p∗n100) %
d. (p+n−(p+n−p∗n100)p∗n100) %
e. (p∗n+(p∗n+(p∗n)21)(p∗n)21) %

-7

step-by-step explanation:

x^2 + 18x + 74 = (x + 9)^2 - 81 + 74

= (x + 9)^2 - 7.

so q = -7.

answer: sorry i can't you.

step-by-step explanation:

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
