Use the method pemdas and you get x=28
Answer:
base=6
Step-by-step explanation:

Answer:
f(x) = -(x-4)^2 + 5
Step-by-step explanation:
The function
is a quadratic function. Its graph looks like a parabola. The graph has a vertex of (4,5) and opens up downward.
Proving that
for all x:

The answer is 280 because if you multiply 400 by .3 you get 120 and if you subtract 120 from 400 you get 280
As there are no parenthesis, Follow PEMDAS and go from left to right
14 x 13 = 182
182/9 = 20.22
20.22 + 8 = 28.22
28.22 is your answer
hope this helps
