Answer:
4 yards 2 feet
Step-by-step explanation:
First we should write the total numbers:
12+8+6+4=30
then we should divide the number 30 by 360(because the pie chart is 360 degrees):

now we should multiply 12(the number of students who likes rock) by 12

the answer is 144 degrees
"The square of x" means x^2, so we can eliminate options A and D.
"product of 8 and x" means that 8 and x are multiplied together (like 8x)
If x^2 is increased by 8x, we are adding x^2 and 8x together.
