If there is a 506,211 pound whale on a scale and you add another whale of 424,809 pounds on the scale how much would they both weigh?
Answer:
Step-by-step explanation:
(2x−3)(3x+6)
=(2x+−3)(3x+6)
=(2x)(3x)+(2x)(6)+(−3)(3x)+(−3)(6)
=6x2+12x−9x−18
=6x2+3x−18
Answer:
<h2>39.36x</h2>
Step-by-step explanation:
Given the f(x) = 12x as the number of inches in x feet and g(x) = 3.28x gives the approximate number of feet in x meters, to find the composite function that can be used to convert metres to inches will give;
f[g(x)] (This means we are substituting the function that is measured in metres into the functions measured in inches).
Given g(x) = 3.28x,
f[g(x)] = f(3.28x)
f(3.28x) means that we are to replace the variable of x in f(x) with 3.28x as shown;
f(3.28x) = 12(3.28x)
f(3.28x) = 39.36x
f[g(x)] = 39.36x
<em>Hence the composite function that could be used to convert meters to inches is expressed as 39.36x.</em>
