the first one is C, I do believe.
the second one is also C, however, I'm not 100% sure on it, but it's worth a shot-
if these are wrong, i'm terribly sorry-
also, please post these in the biology section next time! °ω°
This is a triangle prism, the base is a square and the four sides are equal triangles.
To find the surface area you need to first find the areas of the triangles, then the square, in the end you have to add them together.
Since we know the area of a triangle is 1/2bh we know that one if the triangle in the figure is
9*16/2=72(in^2)
there are four of these so we multiply it by 4
4*72=288(in^2 aka squared inches)
Then we need to find the area of the square. side * side=9*9=81 (in^2)
Add them together we get the surface area.
288+81=369 (in^2)
Answer:

Step-by-step explanation:
The future value formula is FV=PV(1+i)^n, where the present value PV increases for each period into the future by a factor of 1 + i. value PV increases for each period into the future by a factor of 1 + i.

fv = future value
pv = present value
r = annual interest rate ( decimal number)
n= period
Answer:
(4 times x) -5
Step-by-step explanation:
Multiply 4 by a number, x, and <em>then</em> subtract 5.
You want to ensure that you're multiplying first before subtracting.
