We can set up an equation: x * (x + 5) = 564, where x is the length of the rectangle we are trying to solve. Using the quadratic formula to solve this, we eventually come up with approximately 21.38 as a value for x. We can verify this by typing 21.38 * (21.38 + 5) into a calculator and seeing that it approximately equals 564.

Marianna [84]

Answer:

The correct answer is d, there are infinitely many solutions.

Step-by-step explanation:

If the variable terms are the same and the constants are the same, the equation has infinitely many solutions.

Ex: 5(3)+5(5)=40                   3+5=8

     5(4)+5(4)=40                   4+4=8

Hope this helps! Brainliest please!

barxatty [35]

Answer:

i dont know if u know the equation for volume but it is length times width times height SO you would multiply 8.25 times 3 times 5

5 times 3 is 15 so u then multiply 8.25 times 15

Galina-37 [17]

Answer:

$28,875

Step-by-step explanation:

The given table is:

\left|\begin{array}{c|cccccc}$Number of Lease Offices&0&1&2&3&4&5\\$Probability&5/32&3/16&3/32&1/4&9/32&1/32\end{array}\right|

The expected probability is derived using the formula: \sum_{i=0}^{5}x_iP(x_i)

Therefore, for the given distribution,

Expected Probability

=(0*\frac{5}{32})+ (1*\frac{3}{16})+ (2*\frac{3}{32})+ (3*\frac{1}{4})+ (4*\frac{9}{32})+ (5*\frac{1}{32})\\=2.40625

If each yearly lease is $12,000

The Expected Yearly Lease for the Whole Building=2.40625 X 12000

=$28,875

I need help please?!!!!!
Ket [755]

Answer:

b)11

since 11^2 is 11*11 = 12

and when you take the square root of 121

we get 11

(in b- √11^2) , it cancels out the square

square root cancels square since they perform opposite functions

Help???<br> Its a two step inequality problem. I dunno what X equals too.
Verizon [17]

Answer:

x \geq -1

Step-by-step explanation:

-4x + 2 \geq -6x

Add 6x to both sides:

-4x + 2 + 6x \geq -6x + 6x

2x + 2 \geq 0

Subtract 2 from both sides:

2x + 2 - 2 \geq 0 - 2

2x \geq -2

Divide both side by 2:

\frac{2x}{2} \geq \frac{-2}{2}

x \geq -1
