Answer:

No Real roots to this Quadratic Equation

Step-by-step explanation:

Our Quadratic equation is given as

x^2+5x+7=0

In order to find that do we have the real roots of a quadratic equation , the Discriminant must be greater or equal to 0. The Discriminant is denoted by D and given by the formula

D= b^2-4ac

Where b is the coefficient of the middle term containing x, a is the coefficient of the term containing x^{2} and the c is the constant term.

Hence we have

a = 1 , b = 5 and c = 7

Calculate D

D=b^2-4ac\\D=5^2-4*1*7\\D=25-28\\D=-3

Hence we see that the Discriminant (D) is less than 0, our answer is no real roots to this quadratic equation.

sergey [27]

Answer:

Distance=45\ miles

Step-by-step explanation:

Let\ distance\ between\ Lucas\ home\ to\ friends\ village=d\\\\Let\ speed\ of\ Lucas's\ cycle=v\\\\Time\ taken=3\ hours\\\\distance=velocity\times time\\\\d=v\times 3\\\\d=3v

Now\ if\ speed\ is\ 5mph\ slower\ \Rightarrow\ speed=v-5\\\\Time\ taken=3+1.5=4.5\\\\distance=velocity\times time\\\\d=(v-5)\times 4.5=4.5v-22.5\\\\d=4.5v-22.5

d=3v...................eq(1)\\\\d=4.5v-22.5.....eq(2)\\\\1.5\times eq(1)-eq(2)\\\\1.5d-d=1.4\times 3v-4.5v+22.5\\\\0.5d=4.5v-4.5v+22.5\\\\0.5d=22.5\\\\d=\frac{22.5}{0.5}\\\\d=45\ miles
