Given that p=x^2-y^2/x^2+xy I. Express p in the simplest form
ii. Find the value of p if x=-4 and y=-6

p = -

Step-by-step explanation:

Given

p = ( factorise numerator and denominator )

x² - y² ← is a difference of squares and factors as (x - y)(x + y)

x² + xy ← factor out x from each term

= x(x + y) , thus

p = ← cancel (x + y) on numerator/ denominator

   = ← substitute x = - 4, y = - 6

   =

   =

    = = -

answer: 38.47 is your answer

step-by-step explanation: hope i you and who ever sees this answer have a great rest of your day : )

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
