Answer:
g(f(x)) =75x² + 90x + 30
Step-by-step explanation:
To find g(fx), all we need to do is to insert f(x) in g(x), that is anywhere x is in g(x), we replace the value of g(x) with x and then simplify
f(x) = 5x + 3 g(x) = 3x² + 3
g(f(x)) = 3(5x + 3)² + 3
Next is to open the parenthesis and then simplify
(5x + 3)² = (5x + 3)(5x + 3) = 5x(5x+3) + 3(5x+3) =25x² +15x +15x+9 = 25x²+30x+9
g(f(x)) = 3(25x² + 30x + 9) + 3
g(f(x)) = 75x² + 90x + 27 + 3
g(f(x)) =75x² + 90x + 30
Answer: 33
Step-by-step explanation:
Angles inscribed in the same arc are congruent, so
Regular price=21$
Discount=35%
Regular price x discount: 21$x35%= 7.35$
New price after discount: 21$+7.35$=28.35$
The price after the discount is 28.35$.
Answer:
55
Step-by-step explanation:
first set up you problem it would look like this 2*11+3*11
now use PEMDAS
so starting with multiplication 2*11 is 22 and 3*11 is 33
now use addition and 22+33 is 55
The answer is d 1/9 because it will repeat like this : 0.11111111111
