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.

Express the sum or difference as a product. sin 4x - sin 6x
allsm [11]
Hello,

Since:
sin (a)- sin(b)=cos( \frac{a+b}{2}) sin( \frac{a-b}{2} )\\

sin(4x)-sin(6x)=-(sin(6x)-sin(4x))=-2 cos(5x) sin(x)\\

Answer:  The two triangles are similar because the angles are congruent.

Step-by-step explanation: If you add the given measures of the angles given, then subtract from 180, the remainder is equal to the measure of the angle given for the other triangle.

180 - (103 + 22) = 55

180 - (22 + 55)  = 103

So both triangles have the same angle measurements.

Square of a binomial x^2+2x+1
garik1379 [7]
To put an equation into (x+c)^2, we need to see if the trinomial is a perfect square. 
General form of a trinomial: ax^2+bx+c
If c is a perfect square, for example (1)^2=1, 2^2=4, that's a good indicator that it's a perfect square trinomial. 
Here, it is, because 1 is a perfect square.
To ensure that it's a perfect square trinomial, let's look at b, which in this case is 2. 
It has to be double what c is.
2 is the double of 1, therefore this is a perfect square trinomial. 
Knowing this, we can easily put it into the form (x+c)^2.
And the answer is: (x+1)^2.
To do it the long way:
x^2+2x+1
Find 2 numbers that add to 2 and multiply to 1. 
They are both 1.
x^2+x+x+1
x(x+1)+1(x+1)
Gather like terms
(x+1)(x+1)
or (x+1)^2.
