Use the quadratic formula to solve. the answer is the third one down
x= -sqrt10 - 4 and sqrt10 - 4
or in their notation above x= -4+/-10--sqrt
Step-by-step explanation:
The first set is equivalent.
We obtain the right-hand side by swapping places of the terms.
Answer:
A)4
Step-by-step explanation:
Assuming all edges are integral values
The most basic right angles triangle with integral edges is
(3,4,5)
as it obeys pythogores theorem
which is


Now, double each edge,it will still remain a right angled triangle since it will still obey pythogores theorem
so the edges are (4,6,10)
⇒4 cm is the short leg of a integral right triangle with hypotenuse 10 cm
Final result :: (2x + 3y) • (2x - 3y)
