Answer:
all this for five points, you're not serious
Well, first, we can conclude that Arc KJ is equal to Arc GH. Add those for 144. Subtract from 360 and divide that answer by 2 to get the arcs of JH and KG. They are 108. The second is 108. Now we can conclude that the triangles are congruent. We can subtract 54 from 90 to get the rest of angle KGH. That would be 36. We can add the angles to figure out that angle H is 90, since 54 and 36 make 90 and subtract from 180. GJH would be 36 since we found out the 90 and 54.
Answer:
So your question was not very clear but with (f+g) im guessing thats f(x)+g(x)
So first we add them x^2+4x-32 + x-4 then we will get x^2 + 5x - 36
Then we need to multiply both
(x^2+5x-36)(x^2+5x-36)
=
(x^2+5x-36)^2
The only reason im not solving it out is because it yields large numbers and you might not understand.
9:21 is the original ratio but the simplest is 3:7
So y = 1/3x + 7, therefore the gradient is 1/3 and the y-intercept is 7.
