Answer:
(f+g)(x) = x^2 +10x +7
Step-by-step explanation:
(f+g)(x) = f(x) +g(x) = (15x +7) +(x^2 -5x)
= x^2 +x(15 -5) +7
= x^2 +10x +7
First one is 4^2 or just 16.
Second one is using√ So what you want to do is 2√16
Hope this helps

Answer:

Step-by-step explanation:
3 ln(p + q) − 2 ln(q) − 7 ln(p)
=ln(p+q)^3- ln(q)^2-ln(p)^7
= ln(p+q)^3-{ln(q)^2+ln(p)^7}
=ln(p+q)^3-ln(q)^2*(p)^7
=ln{ (p+q)^3÷(q)^2*(p)^7}
=
