Answer:
The AA method
Step-by-step explanation:
The AA method states that if 2 of a triangle's angles are congruent to that of another triangle's 2 angles, then those triangles are similar.
Hence the correct answer is:
D. 6=6; infinite real solutions
Further explanation:
In order to find the simplified form of the equation we have to isolate the variable on one side of the equation.
Given equation is:

Taking 3 common on left hand side

The equation has infinite real solutions.
Hence the correct answer is:
D. 6=6; infinite real solutions

Answer:
height: 7 in
base: 14 in
Step-by-step explanation:
Let the height of the triangle equal x. This means that the base can be represented by the expression 2x. Now we plug these values into the area formula for a triangle:
A = bh / 2
49 = x * 2x / 2
And simplify
49 = x^2
We can find the square root of both sides to get x = 7, so the height is 7 inches. Since the base is twice the height, it is 14 inches.

2. 
Step-by-step explanation:
1. Just subtract them. (To subtract easier, ignore the variables and subtract regularly. When you're done go back and put the variables back in)
