Explain why please and make sure it is in full detail

Marysya12 [62]

Step-by-step explanation:

well,

(y - 7)² = (y - 7)(y - 7)

remember how to multiply 2 expressions ?

you have to multiply every term of one expression with every term of the other expression and sum the results all up (incl. considering their individual signs, of course).

so, when we do the multiplication, we get

(y - 7)(y - 7) = y×y - 7×y - 7×y + (-7)×(-7) =

= y² - 14y + 49

and that is clearly different to y² - 49

FYI

y² - 49 is the result of

(y - 7)(y + 7)

because

y×y + 7×y - 7×y + (-7)(7) = y² - 49

A debt of $9,388.81 is repaid by payments of $1,160.62 in 4 months, $1,178.29 in 13 months, and a final payment in 23 months. If

____ [38]

Answer:

after 4 months $8352.96

AFTER 13 MONTH $7426.507

AFTER 23 MONTH A = 7675.69

Step-by-step explanation:

Given data:

P = $9388.81

Compound interest cab be determined as

A = P( 1+ r/n)^(nt)

after 4 months

$A = 9388.81 ( 1+ \frac{4}{100})^{2\times \frac{4}{12}}$

A = 9513.58

But he has to pay $1160.62 after 4 month so remaining amount is

P = 9513.58 - 1160.62 = $8352.96

AFTER 13 MONTH, so total time is 9 month

$A = 8352.96 ( 1+ \frac{4}{100})^{2\times \frac{9}{12}}$

A = 8604.79

But he has to pay $1178.29 after 13 month so remaining amount is

P = 8604.79 - 1178.28 = $7426.507

AFTER 23 MONTH so total time is 10 month

$A = 7426.50 ( 1+ \frac{4}{100})^{2\times \frac{10}{12}}$

A = 7675.69
