the width of a rectangle is half as long as the length. The rectangle has an area of 98 square feet. What are the length and wid

Andrews [41]

Let's call them: W and L

Then area: A = W × L

We can replace: L = 2 × W

So: A = W × 2W=98→

2W^2=98 →W^2=98/2=49

→W=√49=7

→L=2×W=2×7=14

Conclusion: The rectangle is 7*14 ft

Hope this helps :)

3x^2-3x<br> ----------- -3<br> x^2-9x<br> please give me the simplified answer + explanation

STatiana [176]

You want us to simplify $\frac{3x^2-3x}{x^2-9x}-3$

first, factor top and bottom
$3x^2-3x=3x(x-1)$
$x^2-9x=x(x-9)$

so we have
$\frac{3x(x-1)}{x(x-9)}-3=$
$\frac{3(x-1)}{x-9}-3$
we want to combine fractions so multiply 3 by $\frac{x-9}{x-9}$
$\frac{3(x-1)}{x-9}-\frac{3(x-9)}{x-9}=$
$\frac{3(x-1)-3(x-9)}{x-9}=$
$\frac{3x-3-3x+27}{x-9}=$
$\frac{24}{x-9}$

the simplified answer is $\frac{24}{x-9}$

For a 2-year loan of $5,000, at 8% compounded quarterly, the effective interest rate is (NOTE: round to the nearest hundredth of

Aliun [14]

Answer:

$i_e =0.1716 = 17.17%$

C.I = $1333.85

Step-by-step explanation:

effective interest rode is $i_e =(1+ \frac{i_m}{m})^{mt} -1$

where

i_e efffective rate of interest

i_m = rate of interest = 8%

m = nu,ner of compoundig period per year = 4

t = used for loan time = 2

$i_e =(1+ \frac{0.08}{4})^{4*2} -1$

$i_e =0.1716 = 17.17%$

b)compound interest is given as

$C.I =P[ (1+ \frac{i_m}{m})^{mt}-1]$

we have P-5000 $

i_m -6%

m =2

t = 4

AFTER PUTTING EACH VALUE WE GET

C.I = $1333.85
