4(-6)
6(-4)
those 2 have the same solution as -4(6)
Answer:
false
Step-by-step explanation:
because real number values of x are not the same
Answer:
56 and ty
Step-by-step explanation:
Write out 7x8, you get 56
Looking at Pascal's Triangle, specifically at the row that starts with 1, 10, etc we see the value 210 in the 4th slot (start the count at 0) since 10-6 = 4
Or you can use the combination formula nCr to get the same result
nCr = (n!)/(r!*(n-r)!)
10C4 = (10!)/(4!(10-4)!)
<span>10C4 = (10!)/(4!*6!)
</span><span>10C4 = (10*9*8*7*6!)/(4!*6!)
</span><span>10C4 = (10*9*8*7)/(4!)
</span><span>10C4 = (10*9*8*7)/(4*3*2*1)
</span>10C4 = 210
Either way, the final answer is Choice C) 210
