BRAINLIEST AND 10 + POINTS

-8

Explanation: so f(g(-1)) basically means f of g of -1. so we plug in -1 for x in g(x) and that equals 2(-1) + 5. so g(x) = 3. now we have f(3) because it’s f(g(-1)). f(3) = 1 - 3^2, which equals -8.

hope this helps!

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm
