If (x-y)² = 121xy , then 2log (x+y) =​

Answer»

*Question:—

→ if (X-y)² = 121xy , then 2LOG (x+y) = ?

*ANSWER:—

From 1 :—

→ (x - y)² = 121xy

→ x² + y² - 2xy = 121xy

→ x² + y² + 2xy = 125xy

→ (x + y)² = 125xy

Applying log on both the sides :—

→ log(x + y)² = log(125xy)

→ 2log(x + y) = log125 + log(x) + log(y) ___(3)

From (2) and (3) :—

→ k = log25

Hope it HELPS you.

A swimming pool has a perimeter of 96 m. The length is 3 m more than twice the width. Find the length and width of the pool.

Answer»

\huge\underline\mathtt\red{Answer:}

Step-by-step explanation:

LET X = length of the pool

then

x+3 = WIDTH of the pool

Remember, the perimeter of any rectangle is:

W + W + L + L

2W + 2L

2(W + L)

So, rewriting the above with our variable we have:

96 = 2(x + x+3)

96 = 2(2x+3)

96 = 4x+6

90 = 4x

22.5 METERS = x (length of pool)

width:

x+3 = 22.5+3 = 25.5 meters (width of pool)

Simplify:(4x2 - 2x) - (-5x2 - 8x).not spam ​

Answer»

Answer:

4X2 - 2x) - (-5X2 - 8X)

4x2 - 2x) - (-5x2 - 8x)= 4x2 - 2x + 5x2 + 8x.

4x2 - 2x) - (-5x2 - 8x)= 4x2 - 2x + 5x2 + 8x.= 4x2 + 5x2 - 2x + 8x.

4x2 - 2x) - (-5x2 - 8x)= 4x2 - 2x + 5x2 + 8x.= 4x2 + 5x2 - 2x + 8x.= 9x2 + 6x.

4x2 - 2x) - (-5x2 - 8x)= 4x2 - 2x + 5x2 + 8x.= 4x2 + 5x2 - 2x + 8x.= 9x2 + 6x.= 3x(3x + 2).

4x2 - 2x) - (-5x2 - 8x)= 4x2 - 2x + 5x2 + 8x.= 4x2 + 5x2 - 2x + 8x.= 9x2 + 6x.= 3x(3x + 2).Answer: 3x(3x + 2)
