We could find the error first, but if we solve the equation, we can compare our answers to find the error. So,
7x + 12 + 3x = 8
10x + 12 = 8
10x = -4
x = -4/10
x = -2/5.
When we compare the two, we see that our second line is vastly different, and we can easily isolate the mistake, finding that it occurs when they disregard the variable in the 3x term and subtract 8 by 3 rather than combining the terms 3x and 7x together.

Step-by-step explanation:
step 1. the area of a circle is A. A = (pi)r^2.
step 2. if the diameter is 8 cm then the radius is 4 cm.
step 3. A = (pi)4^2
step 4. A = 16(pi) = 50.24 cm.
In this case, the zebra growth will increase 7% every year which means the growth will increase every year since its count from total population. When there is increased in growth, that will make the graph not linear.
With x-axis represent year and y-axis represent number of zebras, the graph will quadratic graph ( U-shape)
