Answer:
It's being divided by 5.
Step-by-step explanation:
In this question, the variable being used in the equation is being divided by 5. This is represented by the / symbol in the equation which is the symbol for division. If we multiply both sides by 5 we can isolate the variable M and get its value like so...
M/5 = -40 ... multiply both sides by 5
M = -200
Therefore in this scenario, the value of M would be -200
A car travels 440km in 15.4 hours -> In 1 hour, the car travel 1/(15.4) the distance.
So in an hour, the car travel : 440 x 1/(15.4) = 28.5714285714... (round to 29)
So, the average speed of the car is approximately 29 km/h
Answer:
You'll need to post the polynomial itself. The degree will be the highest exponent, the leading coefficient will be the number in front of the variable of the term with the highest exponent, then count the number of terms separated by + and - signs.

Answer:
8.1
Step-by-step explanation:
Use Pythagoras to find the length of BD- 7.5^2 +5^2=81.25
The square root of 81.25 is 9.01
BD-9.01 cm
Then use the cos rule to find BC.
c=a2+b2﹣2abcosγ=9.012+132﹣2·9.01·13·cos(38°)≈8.09819(square root)
round to 8.1
