Solve four square root of six plus eight square root of four and explain whether the answer is rational or irrational.
Inga [223]

Answer:

4\sqrt{6}+16

Step-by-step explanation:

Given the expression: 4\sqrt{6}+8\sqrt{4}

\sqrt{4}=2\\$Therefore, \\4\sqrt{6}+8\sqrt{4}  =4\sqrt{6}+8*2\\  =16+4\sqrt{6}

We can re-write the answer as:

4\sqrt{6}+16

The answer is irrational because the sum of a rational number and irrational number is an irrational number.

<u>The correct option is B.</u>

Find X intercept of f(x)=2(x-4)^2+2
Fofino [41]

Step-by-step explanation:

f(x) = 2( x - 4) ^{2}  + 2 \\ f(x) = 2({x}^{2}  - 8x + 16) + 2 \\ f(x) = 2 {x}^{2}  - 16x + 32 + 2 \\ f(x) = 2 {x}^{2}  - 16x + 34

Which expressions represent the area of the entire shaded region, including the light and dark shading? select three options. 12
Alex Ar [27]

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.
