Answer:
Positive
Step-by-step explanation:
This is the concept of algebra. Given that f(x)=3x+10x and g(x)=5x-3, then:
(f+g)(x)
=f(x)+g(x)
=3x+10x+5x-3
=18x-3
the answer is B. (f+g)(x)=(18x-3)

First we need to find how far away the base of the ladder is from what it is leaning against. The ramp is the hypotenuse and the height from the ground in a leg. Let’s use Pythagorean’s theorem.
a^2 + b^2 = c^2
Substitute
a^2 + (5)^2 = (20)^2
Solve for a^2
a^2 = (20)^2 - (5)^2
Solve for a
a = 5 √15
The slope will be rise over run
5/5 √15 = √15/15 or 0.258…
we know that
a1=7
r=2
n=14
then
Sn=a1*[(r^n)-1]/(r-1)-------------->S14= 7*[(2^14)-1]/(2-1)=114681
the answer is 114681
