Please foil (x^2 - (1/5x^2))^2

Mathematics
1 answer:
Airida [17]3 years ago
8 0




(x² - (1/5x²))²

Using (a-b)² = a²-2×ab+b²

(x²)² -2x²×(1/5x)² + (1/5x²)²

x⁴ -2x⁴ + 1/25⁴

We developed the fraction to obtain the lowest common denominator

x⁴/1 - 2x⁴/5 +x⁴/25

25×(X⁴)/25×1 - 5×(2x⁴)/5×5 + x⁴/25


25×⁴/25 - 10x⁴/25 + x⁴/25

{25×⁴- 10x⁴ + 1x⁴}/25

{26×⁴- 10x⁴}/25

{26×⁴- 10x⁴}/25

16x⁴/25

The width of a rectangle is 6 m shorter than its length. If the perimeter of the rectangle is 52 m, find its length and width.
sineoko [7]

Answer:

Length = 16 m , width = 10 m

Step-by-step explanation:

Let the Length of the rectangle be L meters.

Now, Width of the rectangle is (L-6) m.

Perimeter of the Rectangle = 52 m

Now, we know that

Perimeter of the Rectangle =  2(L+W)

⇒ 2(L+W) =  52 m

or, 2(L + (L-6)) = 52 m

Simplifying, we get 2L + 2L -12 = 52

or, 4L = 64

or, L = 16 m

So, width = L- 6 = (16-6) m = 10 m

So, length = 16 m

and width = 10 m

Un grupo de turistas gasta $ 153 para alquilar tubos y aletas. Se alquilan un total de 12 snorkels y 15 pares de aletas. Alquila
Anettt [7]

Answer:

The cost to rent a snorkel is 9$

(<em>espanol</em>) el costo de un snorkel es de 9$

Step-by-step explanation:

(English)Given that the group of tourists have spent $153 in renting snorkels and fins and there are 12 snorkels and 15 pairs of fins being rented, allow x to be the amount paid for the rent of the snorkels and y to be the rent for pairs of fins then 12x + 15y = 153. Given also that the rent for a snorkel is three times the rent of a pair of fins then x = 3y then, 12(3y) + 15y = 153. Simplify the equation, 36y + 15y = 153. 51y = 153. Solve for y by dividing both sides of the equation by 51 then, y = 153/51 = 3. Therefore, renting a pair of fins costs $3. To compute for the rent of a snorkel, use the equation x = 3y then, x = 3($3) = $9.

(Espanol) Dado que el grupo de turistas han gastado $153 en el alquiler de snorkels y aletas y hay 12 snorkels y 15 pares de aletas que se alquilan, permitir x para ser la cantidad pagada por el alquiler de los snorkels y y para ser el alquiler para pares de aletas entonces 12x + 15y 153. Dado también que el alquiler para un snorkel es tres veces el alquiler de un par de aletas y luego x a 3y, entonces, 12 (3y) + 15y a 153. Simplifique la ecuación, 36y + 15y a 153. 51y a 153. Resuelva para y dividiendo ambos lados de la ecuación por 51 entonces, y á 153/51 a 3. Por lo tanto, alquilar un par de aletas cuesta $3. Para calcular el alquiler de un snorkel, utilice la ecuación x á 3y, a continuación, x a 3($3) a $9.
