If a and b represent the height and base of the triangular face, and h represents the length of its hypotenuse, and w represents the width or thickness of the prism, the surface area (A) is
.. A = ab +w*(a +b+ h)
Of course the area of each triangle is (1/2)ab, but there are two of them, so their total area is ab.
Put in the numbers and do the arithmetic. If you have a lot of them all specified in this way, a spreadsheet can make short work of it.
A = 5*12 +4*(5 +12 +13) = 160 . . . square inches
Slope is cost per arrangement so 3+10d
0 arrangements cost 0 dollars so there is no y-intercept.
Thus we get C=(3+10d)x where x is the number of arrangements

Answer:
(2a-5)² is the final solution
Step-by-step explanation:
4a²-20a+25
= (2a)² - 2 × 2a × 5 + 5²
= (2a-5)²
This is the concept of volumes of solid materials, to get the amount of wax needed to make the candle we will require to calculate for the volume of the candle.
volume=πr^2h
since we are given the circumference of the candle we need to get the radius first;
C=πd
C=31.416 cm
31.416=πd
d=31.416/π
d=10.0000 cm
Therefore the radius will be 5 cm.
The volume of the wax required to make the candle will be:
V=πr^2h
V=π*5^2*13
V=1,021.02 cm^3
