<span>Part A
</span>The variables would be x and y where as the coefficients would be 25 and 100
Part B
There are two terms in the expression, those being 25x and 100y. This is because s plus or minus sign separates terms, and in this case, we only have one plus sign.
<span>Part C
</span>The term that represents the total earnings from mowing lawns in 100y, because the prompt says that he earns $100 mowing lawns.
Answer:
pi^2
Step-by-step explanation:
If the diameter of a circular rug is 2 feet, we can determine that the rug's radius is 1 foot. We can apply the formula to find the area of a circle
(pi*radius)^2 which would give us and answer of pi^2
Converting degrees to radians is easy if you remember,

So anytime you have an angle, just divide by 180 and put pi on the end.
Answer:
c) x = 20, angle COD = 70 °
Step-by-step explanation:
(x+50)° + 90° +20° = 180°
x + 160° = 180°
x = 180°- 160°
x = 20
Angle COD = (x+50)° = (20 +50)° = 70°
Hope this helps
