F(x)=22xplus 33 and ​g(x)=x2−44x−55​, find ​(g◦​f)(88​)
Law Incorporation [45]
F(x) = 22x + 33
g(x) = x² - 44x - 55
(g о f)(88) = (22(88) + 33)² - 44(22(88) + 33) - 55
(g о f)(88) = (1936 + 33)² - 44(1936 + 33) - 55
(g о f)(88) = (1969)² - 44(1969) - 55
(g о f)(88) = 3,876,961 - 86,636 - 55
(g о f)(88) = 2,790,325 - 55
(g о f)(88) = 3,790,270

Draw fraction strips to add 1/4 and 1/6 Write an equation.
Goryan [66]

Answer:

fraction strips would just be;

1 box split into 12 parts because 12 is the common denominator, and 1/4 is equal to 3/12, so you would shade in 3 of the parts, and then 1/6 = 2/12, so you would shade in 2 parts. In the end, you should have a box (or rectangle) with 12 parts, and only 5 of those parts should be shaded in.

The equation would be as follows:

1/4+1/6 = 3/12+2/12 = 5/12

Hope this helped!! :)
