There are 42 students and 30 slices of pizza so 42-30=12 so you would need another extra large pizza to feed the whole class.
Hope this helps!
Find the greatest common factor. For this it would be 11/4
Hello from MrBillDoesMath!
Answer:
Choice D.
Discussion:
Substitute x = 9 in the choices
A. when x = 9, x^2 - 6x + 9 = 36
B. when x = 9, x^2 + 16x + 63 = 288
C. when x = 9, x^2 + 14x + 45 = 252
D. when x = 9, x^2 -12x + 27 = 0
Thank you,
MrB
Area of a circle using the radius is pi*r^2, so:
A=3.14*4^2
A=3.14*16
A=50.24
