Fire and sun light
Answer:
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
= 
= 
=
= - 
Using empirical rule,
Upper range of 68%=15+5=20
Lower range =10
Range=10
-4x+8z is the combined like terms
