Answer:
x^(-5)+4x+1
given f(x)=4x+1 and g(x)=x^(-5)
Step-by-step explanation:
f(x)=4x+1
g(x)=x^(-5)
(f+g)(x) means you are just going to do f(x)+g(x)
or (4x+1)+(x^(-5))
There are absolutely no like terms so it can't be simplified. We can use commutative and associative property to rearrange the expression.
x^(-5)+4x+1
I assume you mean the mixed number 1 + 7/9.
As an improper fraction, we have
1 7/9 = 1 + 7/9 = 9/9 + 7/9 = (9 + 7)/9 = 16/9
Then the square root of this is
√(1 7/9) = √(16/9) = √(4²/3²) = √((4/3)²) = 4/3
Answer:
12s^2 - s - 20
Step-by-step explanation:
It's simplest form is when it's fully expanded.
To expand: (3s-4)(4s+5)
(3s * 4s) + (3s * 5) + (-4 * 4s) + (-4 * 5)
= 12s^2 + 15s -16s -20
= 12s^2 - s - 20
