What is the surface area of this triangular prism? The base of each triangle is 42 m and the height of the triangular base is 20
shutvik [7]

<u>Given</u>:

The base of each triangular base is 42 m.

The height of each triangular base is 20 m.

The sides of the triangle are 29 m each.

The height of the triangular prism is 16 m.

We need to determine the surface area of the triangular prism.

<u>Surface area of the triangular prism:</u>

The surface area of the triangular prism can be determined using the formula,

SA=bh+(s_1+s_2+s_3)H

where b is the base of the triangle,

h is the height of the triangle,

s₁, s₂ and s₃ are sides of the triangle and

H is the height of the prism.

Substituting the values, we get;

SA=(42)(20)+(42+29+29)(16)

SA=840+(100)(16)

SA=840+1600

SA=2440

Thus, the surface area of the triangular prism is 2440 m²

Given: F(x) = 3x^2+1, G(x) = 2x - 3, H(X) = x<br> Find F(x) + G(x) =
weqwewe [10]

F(x)+G(x)=3x^2+2x-2.

Solution:

Given data: F(x)=3x^2+1 and G(x)=2x-3

To find F(x) + G(x):

Adding two functions which gives another function.

Substitute F(x) and G(x), we get

F(x)+G(x)=(3x^2+1)+(2x-3)

                    =3x^2+1+2x-3

                    =3x^2+2x-3+1

                    =3x^2+2x-2

F(x)+G(x)=3x^2+2x-2

Hence, F(x)+G(x)=3x^2+2x-2.
