Determine whether n^2 - 10n - 25 is a perfect square trinomial.
If so, choose the correct factorization.

A. yes; (n - 5)
B. yes; (n + 5)2
C. yes; (n + 5)(n-5)
D. no

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13

step-by-step explanation:

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3

x=-7

step-by-step explanation:

x+3=-10

-10+3=-7

x=-7
