2 answers:
Answer:
The factored form is(k+3h)(k-3h)
Step-by-step explanation:
The given expression is 
Write this expression in difference of squares form

Use the difference of squares formula: 
Here,
a = k
b = 3h
Thus, we have

Therefore, the factored form is(k+3h)(k-3h)
The factored form of this expression would be :
(k-3h)(k+3h).

Step-by-step explanation:
The student should compute 6*180 = 1080 because of the formula
S = 180(n-2)
We have n = 8 sides which leads the n-2 part to become n-2 = 8-2 = 6

Answer:
n=13/7
Step-by-step explanation:
2n+4+6*2=-9*2+8(2n+1)
2n+4+12=-18+16n+8
16+18=16n-2n+8
34=14n+8
34-8=14n
26=14n
n=13/7
