1/2 an hour times 2 is 1 ( an hour)
1/8 times 2 is 2/8
she can read 2/8 of a book in an hour
2x³+18x²<span>-18x-162 =
2(</span>x³+9x²-9x-81)=
2(x²(x+9)-9(x+9))=
2(x²-9)(x+9)=
2(x+3)(x-3)(x+9)
Answer: k=3

Answer:
36 cm
Step-by-step explanation:
Let x represent the multiplier of the ratio units. Then the perimeter is the sum of the side lengths:
77 = 25 + 4x +9x
52 = 13x . . . . . . . . subtract 25
x = 4 . . . . . . . . . divide by 13
4x = 4(4) = 16 . . . . find the other side lengths
9x = 9(4) = 36
The side lengths are 25 cm, 16 cm, 36 cm. The longest side is 36 cm.
