0=138^2+2(-1.4)2pi*n

0 = 13 8^{2} + 2 \cdot (- 1.4) \cdot 2 π \cdot n

n = \frac{23805}{7 π}

Decimal Notation

n = 1082.48097 \dots

Solution steps

0 = 13 8^{2} + 2 (- 1.4) \cdot 2 πn

Switch sides

13 8^{2} + 2 (- 1.4) \cdot 2 πn = 0

Remove parentheses:

(- a) = - a

13 8^{2} - 2 \cdot 1.4 \cdot 2 πn = 0

Multiply the numbers:

2 \cdot 1.4 \cdot 2 = 5.6

13 8^{2} - 5.6 πn = 0

13 8^{2} = 19044

19044 - 5.6 πn = 0

Multiply both sides by

10

190440 - 56 πn = 0

Move

190440

to the right side

- 56 πn = - 190440

Divide both sides by

- 56 π

n = \frac{23805}{7 π}

\frac{z + 6}{3} = \frac{2 z}{4}

16 x - [3 x - (6 - 9 x)] = - 30 x - [- (3 x - 2) - (x - 3)]

3 (x + 1) - 2 (3 x - 1) = 5 (x - 2) + 7

y = - 2 (1)^{2}

7 = - 13 + x
