Step-by-step explanation:

X2+8x+12=0

or, X2+(2+6)X+12=0

3. The price of a pair of shoes is $64.00 plus 9% sales tax. What is the sales tax on this pair of shoes in dollars and cents? A

Luden [163]

Step-by-step explanation:

To figure out this answer, you need to figure out how much 9% is in $64.00

? 9

------- = --------

64 100

Now to solve this you have to multiply diagonally and divide the neighbor

(let me explain)

basically in this case, you would multiply 64 and 9, then divide by 100

64 * 9 = 576

576 / 100 = $5.76

In short: your answer is 'A' $5.76

Hope this helps <3

You deposit $1,200.00 into an account and in three years of simple interest you have $1,380. What interest rate are you receivin

Tcecarenko [31]

Since simple interest doesn't involve compounding, the same amount gets added on every year. So, the equation for the simple interest received is $I = Prt$ , where $I$ is the total interest, $P$ is the original deposit (or "principal"), $r$ is the interest rate, and $t$ is the time passed in years.

Plugging in our values, we can solve for the interest rate:

$I = Prt$
$\$1380 - \$1200 = (\$1200)(r)(3 years)$
$\$180 = (\$1200)(r)(3 years)$
$r = .05 = \bf 5 \%$
