Range is all y-values. This would be all real numbers or (-oo,oo)
Ways to spot if an expression is not a polynomial:
1) If there is a negative exponent
2) If there is division by a variable
3) If the power is something other than a non-negative integer
If any of these conditions exist, the expression will not be a polynomial. Now consider the options. Option A has negative exponent, Option B involves division by a variable and Option D has a exponent which is not a number.
So, from the given options, option C is the only polynomial
Answer:
w = 2
Step-by-step explanation:
6w + 4w - 9 + 6 = 9w - 7+ 6
6w + 4w - 9w = - 7 + 6 + 9 - 6
w = 2
For 3. he answer is a
for 4 the answer is two
The longest side
Think about it. The widest angle would leave a resulting long side to reach the ends of the angle
If you look at the picture, the side across from the widest angle has the longest length
