43.8 = 20. 5^{2} + b^{2}

b = \frac{149819}{10}, b = - \frac{149819}{10}

Decimal Notation

b = 38.70645 \dots, b = - 38.70645 \dots

Solution steps

43.8 = 20. 5^{2} + b^{2}

Square both sides:

1918.44 = 420.25 + b^{2}

1918.44 = 420.25 + b^{2}

Solve

1918.44 = 420.25 + b^{2} : b = \frac{149819}{10}, b = - \frac{149819}{10}

b = \frac{149819}{10}, b = - \frac{149819}{10}

Verify Solutions:

b = \frac{149819}{10}

True

, b = - \frac{149819}{10}

True

The solutions are

b = \frac{149819}{10}, b = - \frac{149819}{10}

1 = x - 3 x - 5

x + 3 + x = - 1

2 b - 3 = 4 + b + 7

9 x - 45 = x - 3

5 x + 4 - 4 x + 9 = 0
