Answer:
(n−9)(n−1)
Step-by-step explanation:
Consider the form x2+bx+c
. Find a pair of integers whose product is c and whose sum is b. In this case,product is 9
and whose sum is −10.−9,−
the factored form using these integers.(n−9)−1 )
Answer: 40 and 52
Step-by-step explanation:
, so both 40 and 52 have a factor of 4.
A heptagon has 7 sides, so 7-2=5
Step-by-step explanation:
F(2)=3(2)²-7
=5
