Answer:
Side A = 39 feet
Side B = 78 feet
Side C = 64 feet
Step-by-step explanation:
Perimeter of a triangle = side A + side B + side C
Perimeter = 181 feet
Side A = x feet
Side B = 2x feet
Side C = x + 25 feet
Perimeter of a triangle = side A + side B + side C
181 = x + 2x + x + 25
181 = 4x + 25
subtract 25 from both sides
181 - 25 = 4x + 25 - 25
156 = 4x
Divide both sides by 4
x = 156 / 4
= 39
x = 39 feet
Side A = x feet
= 39 feet
Side B = 2x feet
= 2(39)
= 78 feet
Side C = x + 25 feet
= 39 + 25
= 64 feet

Step-by-step explanation:
Answer: (x-3)(2x+1)(8)
Step-by-step explanation: First factor out the 8 to get (8)(2x^2-5x-3). So now we have what number multiply out to -6 (ab) and add up to -5. -2 and -3 work out so we manipulate the equation like (8)(2x²-2x-3x-3). Factor out 2x in the first term and -3 in the second and keep going.
