All sides of a square are equal, so set the two equations equal to each other and solve.

5x - 8 = 3x + 14

2x - 8 = 14

2x = 22

x = 11

Form an inequality since it is a square

5x-8=3x+14

you then need to subtract 3x from both sides

2x-8=14

Add 8 to each side

2x=22

divide by 2

x=11

Hope this helped

Solve the equation using the quadratic formula. X^2-9x+3=0
Nesterboy [21]

Answer:

The answer is x= \frac{9+\sqrt{69}}{2}, x= \frac{9-\sqrt{69}}{2}

Step-by-step explanation:

x^2=a

-9x=b

3=c

Plug into formula.

Equation: \frac{9+-\sqrt{(-9)^2-4(1)(3)}}{2}

Simplify the equation.

Equation: \frac{9+-\sqrt{81-12}}{2}

Subtract 81 and 12.

Equation: \frac{9+-\sqrt{69}}{2}

Spit into two equations

Equation 1: \frac{9+\sqrt{69}}{2}

Equation 2: \frac{9-\sqrt{69}}{2}

Hope this helps!

a culture started with 6,000 bateria after 6 hours,it grew to 7,200 .predict how many bacteria will be present after 17 hours ro
Genrish500 [490]

Answer:

10058

Step-by-step explanation:

The equation is of the form

y = ab^x

Where a is the initial value, y is the final  amount and x is the time

y = 6000 b^x

7200 = 6000 b^6

Divide each side by 6000

7200/6000 =  b^6

1.2 = b^6

Take the 6th root on each side

1.2 ^ 1/6 = b^6 ^ 1/6

1.030853321 = b

y = 6000 (1.030853321) ^ x

Let x = 17

y = 6000 (1.030853321) ^ 17

y=10057.68696

Rounding to the nearest whole number

y = 10058
