Step-by-step explanation:
The <span>lateral surface area of a </span>prism
=sum of the areas of its lateral faces.
The <span>total </span>surface area<span> of a prism </span>is the sum of the areas of its lateral faces and its two base
<span> lateral surface area of a right prism is </span><span>L.S.A.=ph</span> p represents the perimeter of the base and h represents the height of the prism.
total surface area<span> of a right prism is </span><span><span>T.S.A.=ph+2B</span><span>T.S.A.=ph+2B</span></span><span> </span>
F(2x-5)=14x-35
G(4x+3x)=14x-5
For this case we have the following system of equations:
5x + 3y = 17
-8x - 3y = 9
We can rewrite the system like:
Ax = b
Where,
A = [5 3; -8 -3]
b = [17; 9]
x = [x; y]
The determinant of matrix A is given by:
lAl = ((5) * (- 3)) - ((3) * (- 8))
lAl = (-15) - (-24)
lAl = -15 + 24
lAl = 9
Answer:
The determinant for solving this linear system is:
lAl = 9
Answer:
The best estimate for the given calculation is 2.8.
Step-by-step explanation:
To determine the correct option regarding the result of this calculation, the mathematical resolution of the same must be developed:
-14 x 1 /9 x (-2 x 9/10) = X
-14 x 1 / 9 x (-18 / 10) = X
-14 x 1 / 9 x -1.8 = X
-14 / 9 x -1.8 = X
-1.555555 x -1.8 = X
2.8 = X
Therefore, the best estimate result for this mathematical operation is 2.8.
