Answer:

y^2 +2x^2 y

----------------------

5 xy^2 - 6 x^2

Step-by-step explanation:

1/x^2 +2/y

-------------------

5/x - 6/y^2

Multiply the top and bottom by x^2y^2 to clear the fractions in the numerator and denominator

1/x^2 +2/y x^2y^2

------------------- * ---------------------------

5/x - 6/y^2 x^2y^2

Distribute

1/x^2 * x^2y^2 +2/y *x^2y^2

---------------------------------------------

5/x * x^2y^2 - 6/y^2* x^2y^2

y^2 +2x^2 y

----------------------

5 xy^2 - 6 x^2

WILL GIVE BRAINLIEST! What is the answer for question (iv)? please help!

Leviafan [203]

Step-by-step explanation:

$\triangle ABC \sim \triangle ADE... (given) \\\\\therefore \frac {AC}{AE} = \frac {BC}{DE}.. (csst) \\\\\therefore \frac {5}{5+2x} = \frac {x+3}{4x+1}\\ \\ \therefore \: 5(4x + 1) = (5 + 2x)(x + 3) \\ \therefore \:20x + 5 = 5x + 15 + 2 {x}^{2} + 6x \\ \therefore \:20x + 5 =2 {x}^{2} + 11x + 15 \\ \therefore \:2 {x}^{2} + 11x + 15 -2 0x - 5 = 0\\ \therefore \:2 {x}^{2} - 9x + 10 = 0\\ \therefore \:2 {x}^{2} - 5x - 4x+ 10 = 0\\ \therefore \:x(2x - 5) - 2(2x - 5) = 0 \\ \therefore \:(2x - 5)(x - 2) = 0 \\ 2x - 5 = 0 \: \: or \: \: x - 2 = 0 \\ x = \frac{5}{2} \: \: or \: \: x = 2 \\ x = 2.5 \: \: or \: x = 2 \\ x = 2.5 \: is \: largest \\ \\ \frac{A(\triangle ABC)}{ A(\triangle ADE)} = \frac{AC ^{2} } {AE^{2} } \\ \\ \frac{A(\triangle ABC)}{ A(\triangle ADE)} = \frac{5 ^{2} } {(5 + 2x)^{2} } \\ = \frac{25}{(5 + 2 \times 2.5)^{2} } \\ = \frac{25}{ {10}^{2} } \\ = \frac{25}{100} \\ \\ \frac{A(\triangle ABC)}{ A(\triangle ADE)} = \frac{1}{4} \\$

Please help me out with this

Naddik [55]

Answer:

(x - 5)² + (y + 3)² = 16

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

here (h, k) = (5, - 3) and r = 4, so

(x - 5)² + (y - (- 3))² = 4², that is

(x - 5)² + (y + 3)² = 16

What is the sum of 3/7, 4/5, and 2/3 rounded to two decimal places

bagirrra123 [75]

Hello!!

Total = 3/7 + 4/5 + 2/3

= 0.428571429 + 0.8 + 0.66666667

= 199/105

= 1.89524.....

≈ 1.90 (rounded to two decimal places)

Good luck :)
