Answer:
D
Step-by-step explanation:
x^2 - 7x + 12 + (x - 3)^2 Add (x - 3)^2 after it has been expanded.
x^2 - 7x + 12 + x^2 - 6x + 9 Combine like terms
2x^2 -7x - 6x + 21
2x^2 - 13x + 21 Factor
(2x - 7)(x - 3)
Which is exactly what D says.
A, C, and D
80 answer is 80
50+30 = 80 answer
Distributive Property.
Use distributive property <em>a(b + c) = ab + ac</em>
4(x + 2) - 3(7 + y) = (4)(x) + (4)(2) + (-3)(7) + (-3)(y)
= 4x + 8 - 21 - 3y = 4x - 3y - 13
