The fraction form is 1369 (5/7)
Step-by-step explanation:
Answer:
(1, 25)
Step-by-step explanation:
Convert to vertex form so that the equation is (x - 1)^2 + 25
If 1 is <em>h </em>and 25 is <em>k</em>, (<em>h, k</em>), the result would be (1, 25)
You just break it up, do 20x8 then another 20x8 then 5x8
Answer:
f(f(x)) = 27
+ 18x² + 4
Step-by-step explanation:
To find f(f(x)) substitute x = f(x) into f(x) , that is
f(3x² + 1)
= 3(3x² + 1)² + 1 ← expand parenthesis using FOIL
= 3(9 + 6x² + 1) + 1 ← distribute parenthesis by 3
= 27 + 18x² + 3 + 1 ← collect like terms
= 27 + 18x² + 4
Answer:
30
Step-by-step explanation:
use Pythagoras theorem
hypothenuse of bottom triangle =√24^2+32^2 = 40
