It looks like you want to find the short leg (x) of a right triangle with long leg 15 and hypotenuse 18. The Pythagorean theorem gives the relationship between the sides of a right triangle.
  18² = 15² + x²
  324 = 225 + x²
  x² = 324 - 225 = 99
  x = √99 ≈ 9.9

The appropriate choice is ...
  b) 9.9

Factor 8x^+10x-8 this ^ is 2
lesantik [10]

Answer:

C) 2(4x² + 5x - 4) is your answer

Step-by-step explanation:

Factor out common factors from all terms.

Note the factors for 8 & 10:

8: 1, 2, 4, 8

10: 1, 2, 5, 10

2 is the largest common factor, and so factor out 2

8x² + 10x - 8 = 2(4x² + 5x - 4)

C) 2(4x² + 5x - 4) is your answer

Note that you cannot factor out anymore common factor numbers or variables.
