<span>Answer: (x + 4)/(x^2 - 3x - 10) * (x - 3)/(x^2 + x - 12) = (x - 3)(x + 4) / (x + 2)(x - 5)(x + 4)(x - 3) = 1/(x + 2)(x - 5)</span>

What is the positive value of “x”?<br> x(x+5)=387<br> Hint: Use the quadratic formula
nadya68 [22]

Answer:

<h2>x= −5−11√13/2, −5+11√13/2</h2>

Solve the equation for x by finding a, b, and c of the quadratic then applying the quadratic formula.

Exact Form:

x= −5−11√13/2, −5+11√13/2

Decimal Form:

x=17.33053201…,

−22.33053201…

Step-by-step explanation:

x(x+5)=387

Simplify

x(x+5).

x^2+5x=387

Subtract 387 from both sides of the equation.

x^2+5x−387=0

Use the quadratic formula to find the solutions.

−b±√b^2−4(ac)/2a

Substitute the values a=1, b=5, and c= −387 into the quadratic formula and solve for x.−5±√5^2−4⋅(1⋅−387)/2⋅1

Simplify.

x=−5±11√13/2

The final answer is the combination of both solutions.

x=−5−11√13/2, −5+11√13/2

The result can be shown in multiple forms.

Exact Form:

x=−5−11√13/2,−5+11√13/2

Decimal Form:

x=17.33053201…,

−22.33053201…

Nancy plans to deposit $1,000 quarterly for 35 years at 8.25% Interest, compounded monthly. How much will she
melomori [17]

Answer:

$17,771.92

Step-by-step explanation:

A = P (1 + r/n)^nt

A = Future value (the answer you're trying to find)

P = Initial deposit ($1000)

R = Interest rate (8.25%; this will be represented as a decimal in the equation (.0825))

N = # of times interest is compounded per unit t (12)

T = Time (35)

35 * 12 = 420

1000 (1 + .0825/12)^420

1000(1.006875)^420

1000*17.77191635

A = $17,771.92 (rounded to the nearest hundredths)

stich3 [128]

Answer:

The correct option is C, i.e., .

Explanation:

It is given that the total number of students in cafeteria should be less than 264. The administrators want there to be 13 less rows than the number of desks in each row.

Let the number of desks in each row be d.

Since administrators want there to be 13 less rows than the number of desks in each row. So the number of row is d-13.

In one row the number of desks is d. So in (13-d) rows the number of number of desks is d(d-13).

Since the total number of students in cafeteria should be less than 264. So we get,
