Answer:

Standard \: form :\:y=  {x}^{2}  - 4x - 5\\Factored\: from:\:y = (x  + 1) (x - 5)

Step-by-step explanation:

y = (x - 2)^{2}  - 9 \\  y=  {x}^{2}   - 4x + 4 - 9 \\   \red{ \boxed{ \bold{y=  {x}^{2}  - 4x - 5}}} \\ is \: in \: standard \: form \\  \\ y = (x - 2)^{2}  - 9  \\ y =  (x - 2)^{2}  -  {3}^{2}  \\ y =  \{(x - 2) + 3\} \{(x - 2) - 3 \} \\ y = \{x - 2 + 3\} \{x - 2- 3 \} \\ \purple{ \boxed{ \bold{y = (x  + 1) (x - 5)}}} \\ is \: in \: factored \: form

Answer: a=2/5b + 1/5c (I may have answered your question but idk if I did)

Step 1: Add -4a to both sides.

9a−2b+−4a=4a+c+−4a

5a−2b=c

Step 2: Add 2b to both sides.

5a−2b+2b=c+2b

5a=2b+c

Step 3: Divide both sides by 5.

5a/5=2b+c/5

a=2/5b+1/5c

2)      Given that n represents the no.of bikes, you just plug it in to the equation below.

250+39(n-1)

= 250+39(20-1)
