Surface Area is the area of each face added together. For this question lets find the area of one triangle first.

Area of a triangle is base*hight/2, so 6*7/2=21. That was the area of one triangle. We have 4 traingle so we multiply that by for. 21*4=84.

Now, lets find the area of the squre. area of square is side*side or side^2.

So we multiply 6*6=36. that is the area of the square.

To find the surface area, we must add Area of Triangles+Area of Square.

so, 84+36=120

So the surface area is 120

Which of the following is the product of the rational expression shown below

wolverine [178]

Option C: $\frac{x^{2}-9}{x^{2}-4}$ is the product of the rational expression.

Explanation:

The given rational expression is $\frac{x+3}{x+2} \cdot \frac{x-3}{x-2}$

We need to determine the product of the rational expression.

<u>Product of the rational expression:</u>

Let us multiply the rational expression to determine the product of the rational expression.

Thus, we have;

$\frac{(x+3)(x-3)}{(x+2)(x-2)}$

Let us use the identity $(a+b)(a-b)=a^2-b^2$ in the above expression.

Thus, we get;

$\frac{x^{2} -3^2}{x^{2} -2^2}$

Simplifying the terms, we get;

$\frac{x^{2}-9}{x^{2}-4}$

Thus, the product of the rational expression is $\frac{x^{2}-9}{x^{2}-4}$

Hence, Option C is the correct answer.

What is the area of this figure?

insens350 [35]

Answer:

54 units squared

Step-by-step explanation:

You have to divide the shape into simpler shapes such as rectangles and triangles that you can easily find the area of. Then, add those areas together. I divided it into one rectangle and three triangles.

Rectangle 1: length=7 width=6 6(7)=42

Triangle 1: base=6 height=2 1/2(6)2=6

Triangle 2: base=3 height=2 1/2(3)2=3

Triangle 3: base=6 height=1 1/2(6)1=3

Area= R1+T1+T2+T3= 42+6+3+3= 54 units squared
