Let a,b and c is side of a triangle where:
a = 1
b = 5
c = 11
a^2 + b^2 = c^2. if the following statement is right, then triangle have these side.
1^2 + 5^2 = 11^2
1 + 25 = 121
26 != 121 ( != means not equal to)
Therefore, triangle can't have side length of 1, 5 and 11 ft.
Answer:

Answer:
105
Step-by-step explanation:
f(x) = 8x² + x -9
g(x) =5x²
(f+g)(x) = 8x² + x - 9 + 5x²
Collect like terms
8x² +5x² + x - 9
13x² + x - 9
b) (f+g)(-3) = 13x² + x - 9 when x =-3
= 13×-3² + (-3) - 9
= (13×9) -3 -9
= 117 -3 -9
= 105
