Answer:
The values of x which would give an area of 240m² would be:

Step-by-step explanation:
Given
The base of triangle b = 2x+1
The height of triangle h = 6x-3
The Area of the triangle A = 240 m²
The Area of the triangle has the formula
A = 1/2 × b × h
substituting b = 2x+1, h = 6x-3 and A = 240



Subtract 480 from both sides




Using the zero factor principle
if ab=0, then a=0 or b=0 (or both a=0 and b=0)

solving


Divide both sides by 2


also solving


Divide both sides by 2


Therefore, the values of x which would give an area of 240m² would be:


As we know that, 1 cm = 0.01 m
So,
(a) 65 cm/s = 0.65 m/s
b) 367 km/h = (367 × 5 ÷ 18) m/s
c) 1000 cm/min = (1000 × 60 ÷ 100) m/s
d) 86 km/min = (86 × 60 ÷ 1000) m/s

The slope of the graph is 3
