- ∆ABD is right angled hence area:-
There is only one option containing 6x^2 i.e Option D.
Hence without calculating further
Option D is correct
First, we need to understand the speed formula:
The time used = distance ÷ rate
In this case, the time needed would be:
5 1/5 ÷ 2 1/6
= (5×5+1)/5 ÷ (2×6+1)/6
=26/5 ÷ 13/6
When there is division in an equaiton, we can swap the nominator and denominator of the fraction amd change it to multiplication:
=26/5 × 6/13
= (13 x 2)/5 x 6/(13 x 1)
Factorize 26 and 13,we get:
=2/5 x 6/1
= 12/5 ft or 2.4 ft
Therefore the answer is 12/5ft or 2.4ft.
Hope it helps!
Answer:
3 feet
Step-by-step explanation:
the ladder makes a 3, 4, 5 triangle with the building and the ground.
Answer:
x = 3 twice
Step-by-step explanation:
x^2 = 6x - 9
Rewrite by subtracting 6x from both sides and add 9 to both sides.
x² - 6x + 9 = 0
Factorise by finding factor of +9 that add up to -6
These factors are -3 and -3 that is
-3 -3 = -6 and -3×-3 = 9
Rewrite equation
x² - 3x - 3x + 9 = 0
x ( x-3) -3(x -3) = 0
Therefore
(x -3)(x-3) = 0
x - 3 = 0 or x - 3 = 0
x = 3 or x = 3
x = 3 twice
