Step-by-step explanation:
For any quadratic equation , the quadratic formula is as follows:
From the given quadratic equation, we know that , and . Plugging in these values into the quadratic formula gives us the following:
180 ÷ 1.5 = 120
Check your answer - 120 × 1.5 = 180
Final answer: 120 miles.
The answer to this will be 10x
Equation 1:This means:
and
Simplifying both the equations we get:
x = 4.5 and x = - 0.5
Equation 2:There is no solution to this equation, as the modulus or absolute value of any expression can never be negative
Therefore, we can conclude that Equation 1 has more number of solutions that Equation 2.
