Answer:
( x + 7 ) ( x + 7 )
Step-by-step explanation:
Product = 49
Sum = 14
Factors = 7 & 7
x² + 14x + 49
( x + 7 ) ( x + 7 )
Answer:
The greatest common divisor of two integers a and b (not both 0) is the largest integer that divides both a and b.
Step-by-step explanation:
Think for example of the numbers a=5, and b= -10. The greatest common divisor of 5 and -10, is the largest integer that divides both 5 and -10. We can find it by inspection (although there are more advanced methods to find it). We can list all integers that divide both 5 and -10.
-5 divides 5, and it also divides -10
-1 divides 5, and it also divides -10
1 divides 5, and it also divides -10
5 divides 5, and it also dividies -10
The LARGEST of them all is then 5, so 5 is the greatest common divisor of 5 and -10. The usual way to write it is

Answer:
5 trips
Step-by-step explanation:
Note that the weight and volume of the load must not exceed the given maximum.
Volume of load = 19.8m^3
Density of load = 650kg/m^3
Mass of load = 19.8 × 650 = 12,870 kg
Given limits.
Volume = 4m^3
Mass = 3700kg
Assuming the truck is to carry 4m^3 of the load.
The mass of 4m^3 of the load is = 4 × 650 = 2600kg
Mass = 2600kg < 3700kg
Therefore it satisfies both conditions.
The number of trip the truck would make is;
N = total volume of load/ volume per trip
N = 19.8/4
N = 4.95
N = 5 trips
The answer is rational, because this number can be written as a over b
