Answer:

Step-by-step explanation:

\frac{5}{4x^2-36} +\frac{8}{2x+6} \\=\frac{5}{(2x)^2-6^2} +\frac{8}{2x+6} \\=\frac{5}{(2x+6)(2x-6)}+\frac{8}{2x+6}\\  =\frac{5+8(2x-6)}{(2x+6)(2x-6)} \\=\frac{5+16x-48}{(2x+6)(2x-6)} \\=\frac{16x-43}{4x^2-36}

A single die is rolled twiceFind the probability of rolling a 6 the first time and a 1 the second time.
Westkost [7]

Answer:

1/36

Explanation:

In a single die, the total number of outcomes = 6

• The probability of rolling a 6 the first time = 1/6

,

• The probability of rolling a 1 the second time = 1/6

Thus, the probability of rolling a 6 the first time and a 1 the second time is:

\begin{gathered} =\frac{1}{6}\times\frac{1}{6} \\ =\frac{1}{36} \end{gathered}

The five interior angles in a  pentagon are in the ratio 2:3:4:5:6. What is the measure of the pentagon's largest angle?
zmey [24]
Let All angles be x times multiplied to ratio , so we"ll get :-

2x + 3x + 4x + 5x + 6x = 540°

20x = 540

x = 540/20

⇒ x = 27 ,

so angles are :-

⇒ 2x = 2×27 = 54°

⇒ 3x = 3×27 = 81°

⇒ 4x = 4×27 = 108°

⇒ 5x = 5×27 = 135°

⇒ 6x = 6×27 = 162°

Hence 162° is the greatest angle

Artyom0805 [142]

Answer:

3/2 cm/s

Step-by-step explanation:

speed = gradient of the line (slope)

To calculate the slope divide the change in y by the change in x:

(9 - 0) / (6 - 0) = 9/6 = 3/2 cm/s
