the ratio of the lengths of strings that play the notes F and G is 9 to 8. If a string 56 centimeters long plays a G, what is the length of the string that plays an F:

answer: what are the answer choices?

step-by-step explanation:

idk what the heck he answer is, i’m just putting this here so i finish my account

"standard form:

3x2 + 14x − 10 = 0

solutions based on quadratic formula:

x1   = −14 − √ 142 − 4×3×(−10) /   2×3   = −14 − 2 × √ 79 /   6   ≈ −5.296

x2   = −14 + √ 142 − 4×3×(−10) /   2×3   = −14 + 2 × √ 79 /   6   ≈ 0.629

the easiest way to do these would be to solve the equations. if you can solve the equation than you can solve these problems.
