3 consecutive odd numbers....x, x + 2, x + 4

P = a + b + c
87 = x + x + 2 + x + 4
87 = 3x + 6
87 - 6 = 3x
81 = 3x
27 = x

x + 2 = 27 + 2 = 29
x + 4 = 27 + 4 = 31

ur 3 sides are 27,29,31...with 31 being the longest

X + (x+2) + (x+4) = 87

3x = 81 -> x = 27

So the longest will be 27 + 4 = 31

The first four sequences are shown below 9,5,1,-3 which of the following functions best defines this sequence

Anvisha [2.4K]

Answer:

Arithmetic sequence.

Step-by-step explanation:

We have been given 9,5,1 and -3

We need to check what kind of sequence is this.

$d=a_2-a_1$

d is common difference we will check difference of consecutive terms.

$5-9=-4$

$1-5=-4$

$-3-1=-4$

We can see the difference between all the terms are same that is -4

So, this is an arithmetic sequence.

Arithmetic sequence is the sequence in which the difference between consecutive terms are same.

Answer: $\frac{2x\sqrt[4]{y^{2}}}{3}$

Step-by-step explanation:

$\sqrt[4]{\frac{16}[81}} \sqrt[4]{\frac{x^{11}y^{8}}{x^{7}y^{6}}}\\\\=\frac{2}{3} \sqrt[4]{x^{4}y^{2}}\\\\=\frac{2x\sqrt[4]{y^{2}}}{3}$
