Step-by-step explanation:
<u>Cars</u>: 
<u>Bikes</u>: 
<u>Total</u>: 
Rounding to the nearest ten: 260
1.
Use this rule: √ab = √a√b
√12√x^2
Simplify √12 to 2√3
2√3√x^2
Simplify √x^2 to x
2√3x^2
3.
Multiply the numerator and denominator by the conjugate.
2√x/x
To the nearest whole number would be 57, because .6 rounds up to the next whole number
