Help also explain please

Answers

Answer 1

Answer: To find surface area we can do 2(l)(w) + 2(l)(h) + 2(h)(w). l = length; w = width; h = height.

Next

Plug in 3 for length, 9 for height, and 13 for width. ( or however you’d like for width length height but only one number can be represented by h, l, and w.)

Then we add all the numbers
2(3)(13)+ 2(3)(9) + 2(9)(13) = SA (surface area)

78 + 54 + 234 = 366 in^2 or 366 sq. inches

Answer 2

Answer:

Final answer:

The given dimensions are of a rectangular prism, and the surface area can be calculated using the formula 2lw + 2lh + 2wh, which gives 366 square inches for a prism with dimensions 13 inches, 9 inches, and 3 inches.

Explanation:

The numbers given, 3 inches, 9 inches, and 13 inches, are usually the dimensions of a rectangular prism, which is a type of box shape. The Surface Area of a rectangular prism is given by the formula 2lw + 2lh + 2wh, where l is the length, w is the width, and h is the height. Based on the numbers given, we can see that :

The length l=13 inches
The width w=9 inches
The height h=3 inches.

So, substitute these values into the formula:

Surface area = 2lw + 2lh + 2wh = 2(13x9) + 2(13x3) + 2(9x3) = 234 + 78 + 54 = 366 square inches.

This means the surface area of the box is 366 square inches. The surface area of a shape is a measure of the total area that the surface of the shape covers.

In the diagram below, AE = 4, EB = 3, and DE = 2. Find CE.

Answers

Answer: Value of CE = 6.

Explanation:

Since we have given that

AE=4

BE=3

DE=2

Let CE be x.

As we know that

When two chords intersect each other inside a circle, the products of their segments are equal.

Here, we can see that each chord is cut into two segments at the point of where they intersect.

So,

$EA.EB=EC.ED\n\n4* 3=x* 2\n\n12=2x\n\n(12)/(2)=x\n\n6=x$

Hence, value of CE = 6.

How do you solve 13y^2-5yx-8x^2

Answers

Answer:

(13y+8)(y-x)

Step-by-step explanation:

13 $y^(2)$ - 5yx -8 $x^(2)$

we can solve above equation by using splitting the middle term

we can factorize it by splitting the middle term

13 $y^(2)$ - 5yx -8 $x^(2)$

=13 $y^(2)$ - 13yx+8yx -8 $x^(2)$

=13y(y-x)+8x(y-x)

=(13y+8)(y-x)

There are the two factors because the degree of the polynomial is 2

Hence, the correct answer is (13y+8)(y-x)

Step 1 :Simplify 13y2-5yx - 23x2
1.1 Factoring 13y2 - 5yx - 8x2 Try to factor this multi-variable trinomial using trial and error Found a factorization : (y - x)•(13y + 8x)
Final result : (y - x) • (13y + 8x)

Radius of a circle with diameter 240mm

Answers

The radius of the circle with the given diameter would be = 120mm.

What is the diameter of the circle?

The diameter of the circle is defined as a line segment that passes through the center of a circle and has two endpoints at the circumference.

The radius is defined as the distance from the centre of a circle to any point on the boundary. The radius:

= Diameter/2

Therefore, the radius of the circle = 240/2 = 120mm
