Answer:
2
Step-by-step explanation:
In general, .
So we have here that:
We went by itself first.
Subtract 441 on both sides:
Multiply both sides by -1:
Take the square root of boht sides:
So both 2 and -2 would satisfy the equation.
Only one of these is a whole number.
The whole numbers consist of the elements that you can count with and 0.
The whole number set is {0,1,2,3,4,5,6,7,...}
So 2 is the answer.
Check:
Replace x with 2:
437=(21+2)(21-2)
437=(23)(19)
437=437 is a true equation so 2 is definitely a solution.
The answer is always negative because if you multiply like signs, the answer is positive, unlike signs are always negative
99 x 0.17 = 16.83 feet every minute
16.83 x 3 = 50.49 meters below the ground
Answer:
True
Step-by-step explanation:
∠a≅∠b
so we can say ∠b +∠c =90
so it is complement
