Step-by-step explanation:
o/-5/-9/8/11
For the first one your equation is h(d)=3/7d+5
If d represents the number of days and the question is wanting to know the height after 1 week (7 days) then you would get this equation once 7 is in the place of d
h(d)=3/7(7)+5
When solved you answer is 8 inch.
For the second one your equation is f(x)=75x+250
If x represents the number of weeks and the question is asking how much money Sam will have after 12 weeks then you will get this equation once putting in 12
f(x)=75(12)+250
Once solved you will get the answer $1150

For a triangular prism, the formula for volume is v=bh where b is the area of the base (72) and h is the height (20). 72x20=1440 so the volume is 1440 cm^3
As for surface area, you want to find the area of each of the faces. For the triangle faces the area is 72. For the three identical rectangle faces the area is 240. 240x3+72x2= 720+144=864cm^2
Hope this helped :)
