*Quadratic equations*<br>solve<br>(i) (x+3)(x-4)=0<br><br>(ii) (2x-3)(x-1) =0​
Ivanshal [37]

Answer:

(i) (x+3)(x-4)=0

  • x+3= 0 ⇒ x= -3
  • x-4= 0⇒ x= 4

(ii) (2x-3)(x-1) =0​

  • 2x-3= 0 ⇒ 2x=3 ⇒ x= 3/2
  • x- 1= 0 ⇒ x= 1

Jane and sali cycled along the same 63 km route.
Alina [70]

Answer:

<em>Sali's speed was 18.75 km/h.</em>

Step-by-step explanation:

Jane took 3.5 hours to cycle the 63 km.

As,  Speed= \frac{Distance}{Time} , so the speed of Jane will be:  \frac{63}{3.5} km/h = 18 km/h

Suppose, the speed of Sali is  x km/h

Sali caught up with Jane when they had both cycled 30 km.

So, <u>the time required for Jane to cycle 30 km</u> = \frac{30}{18}=\frac{5}{3} hours and <u>the time required for Sali to cycle 30 km</u>  =\frac{30}{x} hours

Given that, Sali started to cycle 4 minutes or (\frac{4}{60}) or (\frac{1}{15}) hours after Jane started to cycle. So, the equation will be.......

\frac{5}{3}-\frac{30}{x}= \frac{1}{15}\\ \\ \frac{30}{x}= \frac{5}{3}-\frac{1}{15}\\ \\ \frac{30}{x}= \frac{24}{15}\\ \\ 24x=450\\ \\ x= \frac{450}{24}= 18.75

Thus, the speed of Sali was 18.75 km/h.
