Solve for v. 144v2 + 76 = 85 Write your answers as integers or as proper or improper fractions in the simplest form.

Answer 1

Answer:

$144 {v}^{2} + 76 = 85 \\ 144 {v}^{2} = 85 - 76 \\ 144 {v}^{2} = 9 \\ {v}^{2} = 9 \div 144 \\ \\ {v}^{2} = \frac{9}{144} \\ \\ {v}^{2} = \frac{1}{16} \\ \\ v = \sqrt{ \frac{1}{16} } \\ \\ v = \frac{1}{4} \: , - \frac{1}{4} \\ \\ v = 0.25 \: , - 0.25$
