The sum of 32 and 5 times a number is 17​
Mrrafil [7]

"Sum of 32 and 5 times a number " translates to:

(32 + 5) × n

Then, it says "is 17"

So, (32 + 5) × n = 17. Let's solve!

32 + 5 = 37

37 × n = 17

To find n, we just divide 17 by 37. However, that equates to a repeating decimal, so it is best to put the answer as:

\frac{17}{37}

What is the length of side x? If necessary, round your answer to two decimal places. 19 12
Valentin [98]

Answer:

D. 14.73

Step-by-step explanation:

According to Pythagoras,

19^2 = 12^2 + x^2

x^2 = 19^2 - 12^2

x^2 = 361 - 144

x^2 = 217

x = \sqrt{217}

x = 14.73

Solve 3x^2 + 6x+15=0
Elden [556K]

Answer:

The solution of given equation is ( - 1 + 2 i ) , ( - 1 - 2 i )

Step-by-step explanation:

Given equation as :

3 x² + 6 x +15 = 0

The value of x fro the quadratic equation a x² + b x + c = 0 is obtained as

x = \frac{-b\pm \sqrt{b^{2}-4ac}}{2a}

So , from given eq , the value of x is now obtain as

x = \frac{-b\pm \sqrt{b^{2}-4\times a\times c}}{2\times a}

Or, x =  \frac{-6\pm \sqrt{6^{2}-4\times 3\times 15}}{2\times 3}

Or, x = \frac{\sqrt{-144} }{6}

∴   x = ( - 1 + 2 i ) , ( - 1 - 2 i )

Hence The solution of given equation is ( - 1 + 2 i ) , ( - 1 - 2 i )  Answer
