5 cm = 2km
Scale= 5 cm : 200000 cm
= 1 : 40000
a. 1 : 40000 = x : 500000
x = 12.5 cm
b.1 : 40000 = 2 : x
x = 80000 cm
x = 0.8 km
First 3 terms are a^2 + n a^(n-)1 b + n(n-1)/2 * a^(n-2) b^2
So q^2 / pr = (n^2 * a^(2n-2) * b^2 ) / (1/2 * a^n * (n(n-1) * a^(n-2) * b^2 )
= n^2 * a^2n-2 * b^2
-----------------------------------
1/2 n(n-1) * a^(2n-2) * b^2
= 2n / n - 1 as required
given p = 4, q=32 and r = 96:-
32^2 / 4*96 = 2n / n-1
2n / n-1 = 8/3
6n = 8n - 8
2n = 8
n = 4 answer
Answer:
6x ² - 10x - 56
Step-by-step explanation:
(3x -7) (2x +8)
To expand this, each term in the first bracket would multiply the other bracket.
3x(2x +8) -7( 2x + 8)
6x ² + 24x - 14x - 56
6x ² + 10x - 56

Answer:
27 kilograms
Step-by-step explanation:
When she was born, she weighed 3 kilograms. If she gained 24 kilograms, then that is the initial value (3) plus the added value (24) and you get her weight, which is 27.
