I’m sorry but I don’t understand this
(x-3)^2=(3x+10)*(x-3) so to solve this u can simply take (x-3) over to the other side so it will; look like this
(x-3)^2/(x-3)=3x+10
then it will be x-3=3x+10
-2x=13
x=-13/2 which is -6.5
Answer: Because
, therefore
.
Answer:

Step-by-step explanation:
This question asks to solve an inequality which can be written as:
Solve for x:
From here we can deduce that the inequality is
when:
or 
We can write the solution as:

Answer:
distance covered in 2 hours = 80 km
distance covered in 1 hour = 80÷2 = 40 km
distance covered in 7/2 hours = 40 × 7/2
= 140 km
(3 1/2hours = 7/2 hours)
