My answer is A (the first graph picture). Here is my explanation.
1. 2x = 24 - 4y (Move the variable to the right side and change the sign)
2. X = 12 - 2y (Divide both sides of the equation by 2)
3. Y = 6 and X = 12 (I used my graphing calculator and A is what I got)
Hope this helps, if not, then I apologize! :)
Answer:

Step-by-step explanation:
we know that
A
right triangle has two equal legs
Let
x-----> the length side of the leg of the triangle
y------> the length side of the hypotenuse


so

in this problem we have

substitute the value of y and solve for x



Answer:
D 28x+40
Step-by-step explanation:
To find the perimeter, we add all the sides
2x+2x+5x+8+4x+10+5x+8+x+2+2x+7x+12 = P
Combine like terms
2x+2x+5x+4x+5x+x+2x+7x+10+8+8+2+12
28x +40
