Answer:
B) 6(x+2y) + 4 = 6x + 12 y + 4
As you know 30/45 = 6/9
So a = 9 makes the equation true
Answer:(7,3)
Step-by-step explanation:
The answer is 10 because all the angles are equal making it a equilateral triangle.
Therefore, the sides are all equal to one another, 3x - 8 = 5x - 20.
You just solve for x and get 6. You then plug in 6 for x and evauluate the equation, getting 10.
1.03=b this makes sense because it increases 3 percent so you add 1 to .03
