A.) Distribute the outside to each term
Remember, when you multiply exponents you add the numbers together
Using y=mx+b
Slope-intercept form:
y=x-1
Point-slope form:
Y+3=1(x+2)
Your answer is correct. Indeed:
- In order to find the degrees per minute, you have to divide the full rotation angle (which is 360deg) by the number of minutes (which is 60):
360deg ÷ 60min = 6 deg/min
- In order to find how many minutes have passed, you subtract the times:
1h50m - 1h25m = 0h25m
- You then find how many degrees correspond to 25minutes:
6 deg/min × 25 min = 150deg
- Lastly, you transform degrees into radiants, through the proportion:
deg : 180 = rad : π
Therefore,
150 : 180 = rad : π
rad = (150×π)/180 = 5π/6
The answer would be B 288 cubic centimeters. I hope this helps!

Answer:
-14
Step-by-step explanation:
-19=6k-4k+9
-19=2k+9
subtract 9 from both sides
-28=2k
-14=k
To check your answer plug 14 in for k
