Hello there,
So by using the formula xy=k just plug in both x and y.
So this would be (7)(3)=k
Which means 21=k
Hope this helped!
The answer is 114, because they are alternate interior angles, so they are equal

Answer:
width = 16 cm
length = 19 cm
Step-by-step explanation:
Let the width be x cm.
Given that length is 3 cm more than width then
length = x+3 cm
area of rectangle = 304 square cm. -----1
area of rectangle is given by
area =length * width
substituting from equation 1 and length and width in terms of x we have
304 = x(x+3)

As length cannot be negative hence x = 16
Thus width = x = 16 cm
length = x+3 = 16+3 = 19 cm
(x² - 1)^-2/3
∛(x² - 1)-²
∛(1/(x² - 1)(x² - 1))
∛(1/(x^4 - x² - x² + 1))
∛(1/(x^4 - 2x² + 1))
1/x^4/3 - 1.25992105x^2/3 + 1
