The expression can be simplified to a polynomial of degree 2.
<h3>How to simplify the expression?</h3>
Here we have the expression:
We can directly simplify this by taking the variable as common factor:
This is a polynomial, as you can see, the maximum exponent is 2, so the degree of the polynomial is 2.

Answer:
4 seconds.
Step-by-step explanation:
Let t be the time in seconds when the cheetah catches the antelope.
-Cheetah's speed is 90ft/s and the antelope's is 60ft/s with a 120ft distance between them.
#The expression of the distance of the two when they catch up is;
#Since the distance of the two will be equal at that point:
Hence, the Cheetah catches the antelope after 4 seconds.
Answer:
8π yards
Step-by-step explanation:
A circle subtends a total angle of 360 ° from its center.The length of an arc is directly proportional to the angle it subtends from the circle's center. The arc's length can therefore be calculated as:
C=πd=2πr
Where C is circumference, d is diameter and r is radius. Given r as 16 yards then the arc length which is equivalent to circumference is given as
