The answer would be C because they say if 3 new students arrived each year.
The new price would be $19.99
29.99 x .6666 = $19.99
(Old price multiplied by discount percentage = new price)
X(x-1)(x^2+4)=(x^2-x)(x^2+4)=(x^4)+(4x^2)-(x^3)-(4x)=(x^4)-x(x^2+4)+(4x^2)
Answer:
y=2
Step-by-step explanation:
first solve those in the brackets then find the square root
2y+3=11
put like terms together
3 goes to the right side
2y=11-3
2=8
y=4
√4=2
y=2
The second step is to keep your x terms on the left and move the constant to the right by subtracting it from both sides.
