Not sure the question but the only one that makes since is Line 1....
3*x^2 =6x^2
3*2x=6x
and the -7 its just in a different form
Answer:
Step-by-step explanation:
The two numbers are 54 and 2
Their sum = 54 + 2 = 56
Their product = 54 x 2 = 108
Answer:
33 m/s

In general, units conversion is done by multiplying by a factor whose numerator and denominator have equal values, but different units. The units in that fraction need to be arranged to cancel the units you don't want and leave the units you do want.
Answer:
137 + x <= 170
Step-by-step explanation:
The following inequality will describe this scenario.
137 + x <= 170
the variable x in this scenario represents the total number of cars that you will purchase. This number is added to the number of toy cars that you already own which is 137. As long as this sum is less than or equal to 170 then your storage case will hold them.
Answer:
Step-by-step explanation:
-The locust population grows by a factor and can therefore be modeled by an exponential function of the form:
Where:
is the population after t days.
is the initial population given as 7600
is the rate of growth
is time in days
-Given that the growth is by a factor of 5( equivalent to 500%), the r value will be 5
-The population increases by a factor of 5 every 22 days. therefore at any time instance, t will be divided by 22 to get the effective time for calculations.
Hence, the exponential growth function will be expressed as:
