Answer:
• 4x^2 + 24x + 36 is perfect square trinomial.
Answer= y = 9
Simplify both sides of the equation
4y-40=-4
add 40 to both sides
4y - 40 + 40=-4 + 40
4y= 36
divide both sides by 4
4y/4 = 36/4
36/4 = y=9
Answer:1. distributive property
2. commutative property (the order of 8x and -24 is swapped)
3. reflexive property ((8-24) = -16; -16 is substituted for 8-24. I prefer "substitution property".)
4. commutative property (the order of 8x and -16 is swapped)
5. distributive property
