Answer:
74.163
Step-by-step explanation:
5x means that 5 should be multiplied by the value of x
Every time a variable is touching a number it means it’s multiplying
5x + 8 = ?
If x = 9, you would multiply 5 and 9 which is 45. You then add 45 and 8
45 + 8 = 53
Therefore 5x + 8 = 53
Hope this helps you! :)
s1+s2>s3 where s1 and s2 are the 2 smaller sides
Choice C is the only 1 that fits
7+13 >18
Answer:
f(x) = 3x⁴ -
- 17x + 
Step-by-step explanation:
To find f'(x), we will follow the steps below:
We will start by integrating both-side of the equation
∫f'(x) = ∫(12x^3 - 2x^2 - 17)dx
f(x) = 3x⁴ -
- 17x + C
Then we go ahead and find C
f(1) = 8
so we will replace x by 1 in the above equation and solve for c
f(1) = 3(1)⁴ -
- 17(1) + C
8 = 3 -
- 17 + C
C =8 - 3 + 17 + 
C = 22 + 
C =
C = 
f(x) = 3x⁴ -
- 17x +
