Please select the correct grouping to factor the following polynomial: NOTE: This is not the final answer.

x2 + xy + 8x + 8y

A) x(x + y) + 8(x - y)
B) x(x + y + 8) + 8y
C) x(x + y) + 8(x + y)
D) x2 + y(x + 8x + 8)

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5

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
