Answer: $351

Step-by-step explanation:

When dealing with added tax you're going to want to turn the percentage into a decimal which will make things a lot easier. 8% is going to be .08. When you turn the percentage into a decimal you want to multiply 325 by .08, this will tell you how much tax is being paid. 325 * .08 is 26, now all you have to do is add 26 to the original price and you'll have the final price which is 351.

Solve for x use the completing the square method x^2+6x=5

Mrac [35]

Answer:

$x_{1} =-3 +\sqrt{14} \\\\x_{2} =-3 -\sqrt{14}$

Step-by-step explanation:

$x^{2}$ +6x-5=0

we divide the coefficient of the X by half :

in this case: 6/2 = 3 , then we do the following

The result obtained is raised to square power: 3^2=9

we sum and subtract by 9 to maintain the balance of the equation:

$x^{2}$ +6x+9-9-5=0

we have:

$(x+3)^{2}$ -9-5=0

$(x+3)^{2}$ = 14

lets apply square root on both sides of the equation:

$\sqrt{(x+3)^{2}}=\sqrt{14}$

we know:

$\sqrt{a^{2}} = abs(a)$

so we have:

abs(x+3)= $\sqrt{14}$

from where two solutions are obtained

$x_{1} + 3 =\sqrt{14} \\\\x_{2} + 3 =-\sqrt{14}$

finally we have:

$x_{1} =-3 +\sqrt{14} \\\\x_{2} =-3 -\sqrt{14}$

Answer:

The answer to your question is FJ = 18

Step-by-step explanation:

Data

FG = 30

FH = 12

HE = 8

JH ║GE

These triangles are similar, so we can use proportions to find the length of FJ.

$\frac{FJ}{FH} = \frac{FG}{FH + HE}$

Substitution

$\frac{FJ}{12} = \frac{30}{12 + 8}$

Simplification

$\frac{FJ}{12} = \frac{30}{20}$

Solve for FJ

$FJ = 12 \frac{30}{20}$

Result

FJ = 18
