X2-7x-18÷x2+8x+12 what is it in lowest terms

1 answer:

5 0

$\dfrac{x^2-7x-18}{x^2+8x+12}=\dfrac{x^2+2x-9x-18}{x^2+6x+2x+12}=\dfrac{x(x+2)-9(x+2)}{x(x+6)+2(x+6)}\\\\=\dfrac{(x+2)(x-9)}{(x+6)(x+2)}=\dfrac{x-9}{x+6}$

Delia has 3 5/8 yards of ribbon. About how many 1/4 yard-long pieces can she cut?

grin007 [14]

Answer: There are 14 long pieces she can cut.

Step-by-step explanation:

Since we have given that

Length of yards of ribbon is given by

$3\frac{5}{8}\ yards\\\\=\frac{29}{8}\ yards$

Length of yards of ribbon pieces need to be cut is given by

$\frac{1}{4}\ yards$

Number of yards is given by

$\frac{\frac{29}{8}}{\frac{1}{8}}\\\\=\frac{29}{2}\\\\=14.5\\\\=14$

Hence, there are 14 long pieces she can cut.

your gym membership cost $33 per month after an initial membership fee. you paid a total of $228 after 6 months. writer an equat

grin007 [14]

Answer:

what i did was multiply 33*6 and got 198 and then 228-198 to find out that the initial fee was 30 dollars. then multiply 33*9+30 to get a 9-month total cost of $327

Step-by-step explanation:

cost = $33 per month + fee

1. c(m) = 33m + f

33(6) + f = 228

198 + f = 228

f = $30 membership fee

c(m) = 33m + 30

2. at 9 months: 33(9) + 30 = $327

hopefully this helps :)

have a nice day !!

Algebra I Evaluate each function. h ( n ) = 2 n − 5 ; Find h ( 2 )

slavikrds [6]

Answer:

$h ( 2 ) = - 1$

Step-by-step explanation:

Two-Variable Functions

A function expresses the relation between two variables in such a way that for each input for the independent variable n, there one and only one value for the function h(n). If it's explicitly given as an equation, then we can use values for n as we wish, and compute the different values of h(n).

The question provides the following function

$h ( n ) = 2 n - 5$

We are required to find h(2), which can be computed by replacing n by the value of 2

$h ( 2 ) = 2 (2) - 5$

$h ( 2 ) = 4 - 5$

$h ( 2 ) = - 1$
