Answer:
1,235,520
Step-by-step explanation:
13P6 = 13!/(13-6)! = 13·12·11·10·9·8 = 1,235,520
__
There are 13 ways to choose the first object, 12 ways to choose the second, 11 ways to choose the third, and so on. The 6th object can be chosen 8 ways.
The total number of permutations is the product of all these ways:
13·12·11·10·9·8 = 1,235,520
0.25 is it in decimal form
49–2ax –a^2–x^2
Extract the negative sign
= 49 - (a^2 +2ax +x^2)
Factor using a^2 + 2ab + b^2 = (a+b)^2
= 49 - (a+x)^2
Factor using a^2 - b^2 = (a-b)(a+b)
= ( 7- (a + x)) * (7 + (a + x))
= ( 7- a - x) * (7 + a + x)
Answer: A--p q Superscript 9
Step-by-step explanation:
step 1: Rewriting the expression algebraically
p times q times q times q times q times q times q times q times q times q
becomes
p x q x q x q x q x q x q x q x q x q
Step 2- Counting the number of the repeated q and writing in exponential form gives
p x q ⁹
the best answer from the option trhat relates to this is Option A--p q Superscript 9
