Answer:
x=7
7-4=3
7+2=9
Step-by-step explanation:
Triangle ABE and Triangle CDB are similar
4*3=12
ABE is 3 times bigger than CDB
3(x-4)=x+2
3x-12=x+2
2x-12=2
2x=14
x=7
7-4=3
7+2=9
Answer:
36
Step-by-step explanation:
because 65 and 79 make up for x
Answer:
The number N of bacteria in a refrigerated food is given by N(T) = 10T^2 - 20T + 600, 2 ≤ T ≤ 20 where T is the temperature of the food in degrees Celsius. When the food is removed from refrigeration, the temperature of the food is given by T(t) = 3t + 2, 0 ≤ t ≤ 6 where t is the time in hours.
