Answer:
C or D
Step-by-step explanation:
Since both the length and the width are tripled, the area will be nine times larger. To counter this, divide by nine. 108/9=12 Divide this by 2 to get one length and one width. You get 6. 1+5=6 and 1 is 4 smaller than 5, so the width of this rectangle is 1 cm and the length is 5 cm.
4!=4*3*2*1=24
11!=11*10*9*8*7*6*5*4*3*2*1=39916800
7!=7*6*5*4*3*2*1=5040

Answer:
(3x2 + 1) • (4x - 1)
Step-by-step explanation:
Equation at the end of step 1 :
(((12 • (x3)) - 3x2) + 4x) - 1
Equation at the end of step 2 :
(((22•3x3) - 3x2) + 4x) - 1
Checking for a perfect cube :
12x3-3x2+4x-1 is not a perfect cube
Trying to factor by pulling out :
Factoring: 12x3-3x2+4x-1
Thoughtfully split the expression at hand into groups, each group having two terms :
Group 1: 4x-1
Group 2: 12x3-3x2
Pull out from each group separately :
Group 1: (4x-1) • (1)
Group 2: (4x-1) • (3x2)
-------------------
Add up the two groups :
(4x-1) • (3x2+1)
Final result :
(3x2 + 1) • (4x - 1)
