Answer:

x = 16

Step-by-step explanation:

4x+45=3x+61

Subtract 3x from each side

4x-3x+45=3x-3x+61

x+45 = 61

Subtract 45 from each side

x+45-45 = 61-45

x =16

Which expressions represent the area of the entire shaded region, including the light and dark shading? select three options. 12

A triangle is a polygon. The total area of the figure can be represented by 12a, (6a+b), and 2b cm².

<h3>What is a triangle?</h3>

A triangle is a polygon with 3 sides and 3 vertices.

Since the area of a single triangle is a cm², and the shape is formed of 12 triangles, therefore, the area of the 12 triangles will be equal to,

$\text{Area of the complete figure} = 12 \times a = 12a\rm \ cm^2$

Given that the area of the complete dark portion is b cm², therefore, the area of the 6 triangles with a cm² of area each, and the black portion can be written as,

$\text{Area of the complete figure} = (6 \times a)+b = (6a+b)\rm \ cm^2$

As the dark portion also consists of 6 triangles with an area of a cm² each and the total sum of this dark area is b cm². Also, the light portion consists of 6 triangles with an area of a cm². Therefore, the total area can be written as,

$\text{Total area} = 6a+6a = b+b = 2b\rm\ cm^2$

Thus, the total area of the figure can be represented by 12a, (6a+b), and 2b cm².

Lisa is standing on a dock beside a lake. She drops a rock from her hand into the lake. After the rock hits the surface of the l

Brilliant_brown [7]

Answer:

Why does math have to make a easily peaceful occurrence painful? Why does Lisa not just CALM DOWN and think, 'oh, the water splashed' instead of 'AHHHHH I need to know exactly how FAR my hAnD was from the WaTeR'?

Here is your answer, good sir (or ma'am):

If the rock is going down at 3 inches per second, then to find how far beneath the surface of the lake the rock was after 5 seconds, just multiply 3*5.

After 5 seconds, the rock is at -15 feet.

To find how far away from Lisa's hand the rock is, we need to add 5 because her hand is 5 feet above the lake's surface.

After 5 seconds, the rock is 20 feet away from Lisa's hand.

(I copied it from another Brainly user... I tried to figure it out but Lisa was just too much for me.)
