Total capacity = sum of the individual production capacities.
Here,
Total capacity = sum of f(m) = (m + 4)^2 + 100 and g(m) = (m + 12)^2 − 50.
Then f(m) + g(m) = (m + 4)^2 + 100 + (m + 12)^2 − 50.
We must expand the binomial squares in order to combine like terms:
m^2 + 8 m + 16 + 100
+m^2 + 24m + 144 - 50
---------------------------------
Then f(m) + g(m) = 2m^2 + 32m + 160 + 50
f(m) + g(m) = 2m^2 + 32m + 210, where m is the number of
minutes during which the two machines operate.
Answer:
0.37
Step-by-step explanation:
Since 20 min is 1/3 of a mile 20 min*3=1 hour. then u multiply 2/5 by 3 to get 6/5.
Answer: b ≤ -18
<u>Step-by-step explanation:</u>
Isolate the variable by multiplying both sides by -3. Remember that when you multiply or divide by a negativem the symbol flips.
2x-3 = 6
2x(-3+3) = (6+3)
2x = 9
(2x ÷ 2) = (9 ÷ 2)
x = 4.5
