The common denominator is 12
Well because 14 is nowhere near half of 950 (which is 475), 1/2 is bigger. I hope this helped.
Volume of cylinder = πr²h = π x 4² x 6 = 96π
volume of cone = 1/3πR²H = 1/3π x 8² x 12 = 256π
You can see that volume of cone is more than twice of volume of cylinder. So she is not correct
Okie, so you have 2 polynomials separated by a plus sign. If there were a number in front of the polynomial, you would need to factor, as well as if there was a negative sign. But there is just an addition sign so you just add as you would normally.
5x + 9 + 3x - 2 = 8x +7
I hope this helps :-)
127 = 100 +27
32 = 30 +2
so 127 x 32 = (100 + 27) x (30+2) = (100x30) + (100x2) + (27x30) +(27x2)
= 3000+200+810+54 = 4064
second way:
127 = 100 + 27
127 x 32 = (100+27) x 32 = (100x 32) + ( 27x32) = 3200 + 864 = 4064
