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
= 
= 
= 
= -
First add y to both sides to get 9x=45+y than subtract 45 from both sides to get 9x-45=y or y=9x-45
<h3>20 subtracted from three times a number is 6 more than the number. Then the number is 13</h3>
<em><u>Solution:</u></em>
<em><u>Given statement is:</u></em>
20 subtracted from three times a number is 6 more than the number
We can translate the sentence into algebraic expression
Let "a" be the unknown number
Then,
20 subtracted from three times "a" is 6 more than "a"
Which means,
3a - 20 = 6 + a
3a - a = 6 + 20
2a = 26
Divide both sides by 2
a = 13
Thus the number is 13
The statements that are true are A, B, and D
