Answer:

The surface area is:

120 {cm}^{2}

Step-by-step explanation:

There are two triangles, and three rectangles in this prism. The area of a triangle is:

\frac{1}{2} base \times height

and the area of a rectangle is:

length \times width

Therefore the area of the triangle is:

\frac{1}{2} (5) \times 12 \\ 2.5 \times 12 = 30 \\ 30 \times 2 = 60

This value is multiplied by 2 because there are 2 triangles.

The area of the slanted rectangle is (13 x 2 = 26), the area of the standing rectangle is (12 x 2 = 24), and the area of the base rectangle is (5 x 2 = 10).

Therefore the surface area of the triangular prism is; 60 + 26 + 24 + 10 =

120 {cm}^{2}

Answer:

Step-by-step explanation:

Surface area formula

= bh + L(s1,s2,s3)

= 5(12) + 2(12+13 +5)

= 120

Therefore the surface are is 120cm

Nutka1998 [239]

Let's look over the meaning of each option:


Theocracy: Theo- means that it is relating to religion. For example, Theology is the study of religion. This is a system where religious leaders control the country, but it is NOT an economic system.

Monarchy: Monarchy is when there is a king, queen, emperor, etc. It is not an economic system either.

Fundamentalism: A political system that strictly abides by a set of fundamentals. Someone who wants a constitution to be the highest form of law is a fundamentalist. However, this is also not an economic system.

Socialism: WINNER WINNER CHICKEN DINNER! Socialism is a system similar to communism where the government controls the economy and there is communal ownership. This is also the only option which is both a political and economic system.


TL;DR: The answer is Socialism.

Answer:

So, C, and D.. can easily be marked incorrect. This is because in the question it asks, "Atleast 16" This leaves us with answer choice A and B. Answer choice (A), is a closed circle, while answer choice (B) is an open circle.

Closed circles include the number at the end point (less than/greater than/equal to), and open circles do not (less than greater than).

answer choice  A. Closed circle, shifting to the right.

Given f(x) = 2x + 3 and g(x) = x - 9, what is f(x) + g(x)?
Orlov [11]
Solution:

f(x) = 2x + 3
g(x) = x - 9

f(x) + g(x)
= (2x + 3) + (x - 9)
= 2x + x + 3 - 9
= 3x - 6
