Answer:
2
Step-by-step explanation:
We can set up equation for this one.
Let's say the number is X.
the sum of X and 14 can be expressed as : X+14
five times the sum of X and 14 can be expressed as 5(x+14)
and 5(X+14) = 80

The number is 2
<span>f(x)=25-x^2 and g(x)=x+5
</span>(f/g) (x)=(25-x^2 )/(x+5)
25-x^2=(5-x)(5+x)
(f/g) (x)=(5-x)(5+x)/(x+5)
cancle out x+5
(f/g) (x)=(5-x)
Assuming this is a rectangular prism, here are the formulas for the volume and surface area.
V=l×w×h
SA=lw+lw+lh+lh+wh+wh
I didn't want to give the answer away, but I wanted to head you in the right direction. Hope this helped!
