Answer:
The factorized expression is
Step-by-step explanation:
The first step to solve this problem is knowing that:
So
The factorized expression is
A square is a special case of many lower symmetry quadrilaterals
Answer:
The probability of getting a nickel, then a dime is 2/21
Step-by-step explanation:
No. of pennies = 9
No. of nickels = 10
No. of dimes = 12
No. of quarters = 5
Total items = 9+10+12+5=36
So, Probability of getting nickel on first draw =
Now the nickle in not replaced
So, Total items = 36-1 = 35
So, Probability of getting dime on second draw =
So, the probability of getting a nickel, then a dime =
Hence the probability of getting a nickel, then a dime is 2/21
Answer:
It is B.

From here we can just FOIL; first, outer, inner, last. Multiply the first term in the first bracket (x), by the FIRST term in the second bracket (x), giving us
x
2
. Then, we multiply the outermost term on the left side by the OUTERmost on the right side, giving us
−

⋅
x
, equal to
−

x
. We then multiply the INNERmost terms together, which are again -3 and
x
, giving us
−

again. Finally we multiply the LAST term in the first bracket by the last term of the second, giving us
−
