(_x2) + (_x3)=12 In four different ways

1 answer:

3 0

If you substitute a variable for each blank, for example x*2+x*3 you get 5x=12, which can then be solved to get that x=12/5, so 12/5 is the answer.

Will give brainliest to correct answer.

Kobotan [32]

Note that c is the hypotenuse of the blue triangle, and that the Pyth. Thm. states that (length of one leg)^2 + (length of the other leg)^2 = (hyp)^2.

Therefore, (hyp)^2 = c^2 = [2sqrt(x^2+3x)]^2 + 3^2, or
= 4(x^2+3x) + 9, or
= 4x^2 + 12x + 9 = (2x+3)^2
Taking the sqrt of both sides, c = plus or minus (2x+3). Eliminate -(2x+3) because the middle term of the square of this would be negative, in conflict with the given +12x.

c=2x+3 is the correct answer.
