Jameson and Quincy each deposit $ 7,000 into accounts that earn 6% interest, but Jameson earned simple interest with Quincy earns annual compound interest. Assuming neither one of them deposits or withdrawals for 60 months, which of the following is a true statement? A. Jameson will have about $ 2,100 more in his account than Quincy.
B. Jameson will have about $ 2,367.58 less in his account than Quincy.
C. Jameson will have about $ 9,367.58 less in his account than Quincy.
D. Jameson will have about $ 2,367.58 more in his account than Quincy.

what answer was it

Step-by-step explanation:

x^2 + 81

we can factor this using difference of square binomials.

rewrite the equation:

x^2 - (-81)

factor:

(a^2 - b^2) = (√a^2 + √b^2)(√a^2 - √b^2)

(x^2 - (-81) = (x + √-81)(x - √-81)

we can remove the - from under the radical by multiplying it by i.

(x^2 - (-81) = (x + i√81)(x - i√81)

(x^2 - (-81) = (x + 9i)(x - 9i)

we can check our answer by using foil:

x^2 - 9ix + 9ix - 81i^2

x^2 - 81^2

i^2 = -1

x^2 + 81

the diagram shows you   triangle def with de=4, df=9 and de≠df≠ef.

the sum of the lengths of two triangles' sides are always greater than the length of the third side:

substitute sides lengths:

then 5< ef< 13 (option 3 is true).

def is a scalene triangle with all sides of different lengths (option 5 is true, option 2 is false).

answer: correct choices are 1, 3 and 5
