Answer:
A = 12 units ^2
Step-by-step explanation:
The area of the trapezoid is found by
A = 1/2 (b1+b2)h
b1 = 2
b2 = 4
h = 4
I found these by looking at the graph
A = 1/2(2+4) 4
A = 1/2(6*4)
A = 12 units ^2
One example is the equation 2x+3x = 5x because the left hand side combines to form the right hand side. This equation is said to be an identity, which is always true for any real number you can think of. For example, if x = 3, then,
2x+3x = 5x
2*3+3*3 = 5*3 ... replace every x with 3
6 + 9 = 15
15 = 15
We end up with a true equation. This will happen regardless of what x value we pick. Therefore, it has infinitely many solutions.
if you're trying to solve for x, and it is equal to zero, then it would be -3. plug it in and it would all cancel out
