We know:

sin(C)=\frac{h}{a}

and

sin(A)=\frac{h}{c}


These expressions have an h term in common. We can combine them if we can find forms of the expressions in terms of h:

h=a(sin(C))

h=c(sin(A))


Now, because h=h (by the reflexive property), we can write:


a(sin(C))=c(sin(A))


This is our answer, A.

4. 6x^2 +14x + 8

Step-by-step explanation:

1. (x-3)(x-6)

x^2 - 6x - 3x +18 = x^2-9x+18

2. (2x+4)(x-4)

2x^2-8x+4x-16 = 2x^2-4x-16

3. (x-7)(3x+2)

3x^2+2x-21x-14 = 3x^2-19x-14

4. (3x+4)(2x+2)

6x^2+6x+8x+8 = 6x^2 +14x + 8
