-∞ ≤ x ≤ ∞
Because x has no limit so it can be between negative infinity and positive infinity. It's just a symbol that lets you know that x can be any number.
Area of rectangle is base times height
area of triangle is 1/2 times base times height
this shape has 3 rectangular sides and 2 triangular sides
2 sides and 1 bottom
2×(6×5)+1×(6×8) = 108
front and back triangular sides
2×(1/2)×(3×8) = 24
total is 132 cm^2, C
Answer:
see below
Step-by-step explanation:
2/3 ÷ 4
We use copy dot flip
The flip means make a reciprocal of the second number
2/3 * 1/4
Multiply the numerators
2*1 = 2
Multiply the denominators
3*4 =12
Put the numerator over the denominator
2/12
Simplify
1/6
4 kilometres is 4000 meters
4000 meters - 3400 meters = 600 meters
and as John is the one that rode 4 kilometres he rode further and by 600 meters
