Answer:
10x^2 -18
Step-by-step explanations
since f(x) is becoming the new x then youd subtitute the equation into the x of the g(x) equation. which would be 5(2x^2 -5) +7 which is 10x^2 -25 +7.and you'd simplify from there.
The square root of 39 is approximately 6.245 so it lies between 6 and 7

Answer:
x < 5
Step-by-step explanation:
What 5 > x means is that the variable x takes values less than 5, we can notice that because the narrow part of the symbol is pointing towards x, which means x is smaller than 5.
Analyzing the options:
- x> 5 this tells us that x takes values greater than 5, which in fact is the opposite of what we are looking for.
- 5 <x this also tells us that x takes values greater than 5, not what we are looking for.
- x < 5 this option does represent the same as 5 > x because in both the narrow part of the symbol points to x, indicating that x is smaller than 5, therefore this is the correct option
