Answer:
9.8 units
Explanation:
According to Pythagoras theorem, the square of length of the hypotenuse is equal to the sum of squares of lengths of other two sides.
Let the third side be x units.
Then,
x² + 10² = 14²
=> x² + 100 = 196
=> x² = 196 - 100
=> x² = 96
=> x = √96
=> x = 4√6
=> x = 9.79....
=> x = 9.8 (Rounding to the nearest tenths)
So, the length of the third side is 9.8 units.
Answer:
therefore the side of the square is 2x + 5.
Step-by-step explanation:
i) let the side of the square be a
ii) therefore the perimeter of the square = 4a
iii) therefore 4a = 8x + 20
iv) therefore a = 2x + 5
therefore the side of the square is 2x + 5.
As the equation does not consists like terms we can only get x , y equations.
Step-by-step explanation:
Firstly, they are not like terms.
If the value to be is found is X then,
8x+5y=4
Now subtract 5y on both sides
8x+5y-5y=4-5y
here both positive 5y and negative 5y get cancelled
Now divide by 8
x=(4-5y)/8
If we need y value then,
subtracting both sides by 8x
5y=4-8x
Now dividing with 5 on both sides
y=(4-8x)/5 =>y=4/5 -8x/5
According to Y=mx+c
slope = m = 4/5
y-intercept = -8x/5.
The first and the difficult thing is you need to tell that
x^2-4xy+4y^2 = ( x - 2y )^2
so from question you know 3x - 6y = x - 2y = 9z
finial : ( x - 2y )^2 = ( 9z )^2=81z^2
so the answer is D . Hope this would help you .
