Answer:
A) −3(x3+2x−1)
Step-by-step explanation:
Factor 3-3x^3-6x to get −3(x3+2x−1)
Answer:
20
Step-by-step explanation:
we can see that there are already answers for 2 which is six 6+6=12 now we can see that a triangle look the same as the six over the 8mm so that must be six so 6+6+6=18 now there is still s little section missing over the 8mm (the half triangle half square) is missing a section we can see that the perimeter is 8 and the area is 6 and 6+2=8 so that little area is 2 so 6+6+6+2=20
9 x 9 = 81
81 - 21 = 60
60 / -6
10
BC/AC = EF/DF
10/20 = 20/DF
DF = 40
AB/BC = DE/EF
AB/10 = 36/20
so AB = 18
answer
AB = 18, DF = 40 (A. fist one is your answer)
The second option is the answer
