F(x)=5/x
g(x)=2(x^2)+5x
f(x) has a domain of all real numbers excluding zero
g(x) has a domain of all real numbers
fog(x)=5/(2(x^2)+5x)
fog(x)=5/(x(2x+5))
fog(x) has a domain that excludes both zero and -5/2
The perimeter of an object is found by adding all of the sides. The sides of his frame would be 2 ft, 2 ft, 1.5 ft (18 inches / 12 inches per foot = 1.5 feet), 1.5 feet. Adding these together we get a total length of 7 feet. However, he may want to use a slightly longer board to account for any errors!
Answer:
<u>X</u> <u>Y</u> <u>(</u><u>X,</u><u>Y)</u>
-4 14. (-4,14)
-3 12. (-3,12)
-2 10. (-2,10)
-1 8. (-1,8)
0 6 (0,6)
1 4. (1,4)
2 2. (2,2)
4b because you distribute the 4 to get 8b - 4b so that equals 4b
