The value of x is 13, from the values of x the values of a,b and c becomes 5, 12 and 13, which is obtained by using Pythagorean theorem.
Step-by-step explanation:
The given is,
a = 5
b = x - 1
c = x
Step:1
Pythagorean theorem is,
................................(1)
( It states that the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides )
From the given values the equation (1) becomes,

(
)
25 + (
+ 1 - 2x ) = 
25 + 1 -2x = 0 ( ∵ Eliminate
in both sides)
26 = 2x
x = 13
Step:2
From the values of x,
a = 5
b = ( 13 - 1 ) = 12
c = 13
Result:
The value of x is 13, from the values of x the values of a,b and c becomes 5, 12 and 13, which is obtained by using Pythagorean theorem.
Answer:
C. 0.038 km² > 3.8 m² > 380 cm² > 3800 mm²
Step-by-step explanation:
Convert every measurement to the same unit, say, square metres.
(a) 3.8 m²
No conversion necessary
(b) 380 cm²

(c) 0.038 km²

(d) 3800 mm²

In decreasing order, 0.038 km² > 3.8 m² > 380 cm² > 3800 mm²
Answer:
31680 feet
Step-by-step explanation:
Total distance walked in 5 days
= 5 × (0.6 miles × 2)
= 5 × 1.2 miles
= 5 × 6336 feet
= 31680 feet
Part 1:
3+2+1 = 6 total units
There is only 1 history book.
1/6 total.
Part 2:
6-1 (we've lost the history book) = 5 total units
3 novels. = 3/5
Part 3:
1/6 * 3/5 = 3/30 or 1/10
