Answer:
Step-by-step explanation:
6 and - 2 are the only two solutions to the required quadratic equation.
So, if the variable is represented by X then (X - 6) and (X + 2) will be the only two factors of the polynomial function.
Therefore, the equation is
(X - 6)(X + 2) = 0
⇒ 
If the leading coefficient of the equation is 3 then we can write the equation as (Answer)
Step-by-step explanation:
Wai 1unit+45
Cheryl 1unit
Zheng 4units+180
Altogether 6units+225=510
6units = 510-225
6units=285
1unit=285÷6
= $47.5
So Wai =47.5+45 = 92.5
Cheryl =47.5
Zheng =4×47.5+180 =370
370-47.5=$322.5
Answer $322.5
(–23) – 45 – (–98) =–23 – 45 +98=-68+98=30
12: 1.8= 20/3. => the answer is 20/3 miles
Answer:
2.72 x 10^4
Step-by-step explanation:
2.4 x 10^4
= 24000
3.2 x 10^3
= 3200
Therefore,
(2.4 x 10^4) + (3.2 x 10^3)
= 24000 + 3200
= 27200
= 2.72 x 10^4
