X+2 is a factor of given polynomial So x=-2 is a zero of that polynomial Now Put the value of x in polynomial X3-6x2+kx+10=0 (-2)^3-6×(-2)^2-k×2+10=0 Or -8-24-2k+10=0 Or -32+10=2k Or -22=2k So K=-11

1)   Circumference:  C = D × π = 40 × 3.14 = 125.6

     Area:  S=r^2.\pi =(\frac{D}{2} )^2.\pi = (\frac{40}{2})^2.3,14=1256\\

2)  Perimeter: P = 10.82 +10.82 + 12 + ( 12 . 3,14 )/2 = 52.48 mm

     Area:  S=\frac{9.12}{2}+(\frac{12}{2} )^2.\pi  = 167.04

Giovanni is visiting her grandmother who lives in an apartment building on the 25th floor. Giovanni enters the elevator in the l
Blizzard [7]
So how many does he have left

25-16=9
9 floors left

the want a percentage so 9 out of 25
percent is out of 100
a hack for this specific problem is that 25 is exactly 1/4 of 100 so
9/25 times 1=the same thing so
9/25 times 4/4 (simplifies to 1)=(9 times 4)/(25 times 4)
36/100
this is out of 100 so
36%

of course there is a legit way of solving this problem but this is a hack (this works for factors of 100 like 2,4,5,10,20,25,50)
