Find the surface area of the composite solid.
Westkost [7]

We have:

4 triangles with the base b = 5ft and the height h = 6ft

4 rectangles with the lenght l = 5ft and the width w = 4ft

1 square with side a = 5ft.

The formula of an area of a riangle:

A_T=\dfrac{1}{2}bh

Substitute:

A_T=\dfrac{1}{2}(5)(6)=\dfrac{1}{2}(30)=15\ ft^2

The formula of an area of a rectangle:

A_R=lw

Substitute:

A_R=(5)(4)=20\ ft^2

The formula of an area of a square:

A_S=a^2

Substitute:

A_S=5^2=25\ ft^2

The Surface Area of composite solid:

SA=4A_T+4A_R+A_S

Substitute:

SA=4(15)+4(20)+25=60+80+25=165\ ft^2

<h3>Answer: The Surface Area of the composite solid is 165 ft².</h3>

2(1 – x) &gt; 2x HELP ASAP!!! I CANT FIGURE THIS OUT
katrin [286]
<h3>Answer:  x < 1/2</h3>

This is the same as saying x < 0.5 since 1/2 = 0.5

====================================================

Work Shown:

2(1-x) > 2x

2*1 + 2*(-x) > 2x ..... distribute

2 - 2x > 2x

2 > 2x+2x .... adding 2x to both sides

2 > 4x

4x < 2 ..... flip both sides; flip the inequality sign

x < 2/4 ..... dividing both sides by 4; see note below

x < 1/2

Note: We do not flip the inequality sign here because we are dividing both sides by a positive value. The inequality sign would only flip if you divide both sides by a negative number.
