Step-by-step explanation:

Option A. is correct.  To calculate the lateral surface area triangular prism, the sides B, C and D are need to be added to calculate the area.

A triangular prism is "a polyhedron made up of two triangular bases and three and three rectangular sides. It has 5 faces, 6 edges and 9 vertices".

According to the question,

Formula for lateral surface area  = (a +b +c)h where a, b, c are perimeter of base and 'h' is height of the triangular prism.

From the given triangular prism has B, C and D are perimeter of base.

Hence, to calculate the lateral surface area triangular prism, the sides B, C and D are need to be added to calculate the area.

Answer:

D. y = -4/5x + 10

Step-by-step explanation:

If you graph it, whether that be on paper or typing the equation out on a website so it can do the graphing for you, it's a straight line with a negative slope unlike the other choices. Therefore, it's a linear function. A quick tip is that, usually, a linear function can be easily shown in the form of y = mx + b (slope-intercept form), and that's the exact form y = -4/5x + 10 is in. y being y (dependent variable, or result/output), -4.5 being m which represents the slope, x being x (independent variable, or input), and +10 being b which represents the y-intercept. If the x is in the denominator like in y = 5/x - 3, it's very likely that it's not a linear function.

Answer: 343.5

Step-by-step explanation: multiply 15 * 17 and you get 255 then divide that by 2 and you get 127.5.

Next you multiply 8 by 27 (which is 216)

Now add 127.5 and 216 and you get 343.5

Answer:

1) 24w + 18
2) 6(4w + 3)

Step-by-step explanation:

Explanation for 1)
Use the Foil method for factoring by multiplying each number inside the bracket [8w + 6] by the number outside the brackets [3]

3*(8w + 6)
3 * 8w + 3 * 6
= 24w + 18

Explanation for 2)
By using the final product in 1) [24w + 18], we can facour it further by using GCF (Greatest Common Factor)

We have to determine first what is the greatest common factor of 24w, and 18

Its 6

So we use 6, and divide it by what we got in explanation 1 to find our 2nd way of writing the expression
24w/6 + 18/6
= 6(4w + 3)

Don't forget to put whatever you divided those numbers by outside of the bracket

Hope this helps :)

Answer:

Step-by-step explanation:

Given

3(8w + 6)

Question

Write in 2 different ways.

Method One

Use the distributive property to remove the brackets.

3(8w + 6)            Given. Remove the brackets. Notice both results

3*8w  + 3 * 6      Combine

24w + 18

Method 2

Take out another common factor. 2 is another common factor.

3(8w + 6)

3*2 (4w + 3)            Combine

6 ( 4w + 3)

The cost of a brush, a sketchbook, and a paint set will be $ 2.38, $ 14.3, and $ 19.067 respectively.

A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.

Genevieve brought $35.75 to the art supply store.

She bought a brush, a sketchbook, and a paint set.

Let x be the cost of the paint set.

The sketchbook cost 3/4 the cost of the paint set. Then the cost of the sketchbook will be

[tex]\rightarrow \rm \dfrac{3x}{4}[/tex]

The brush was 1/6 as much as the sketchbook. Then the cost of the brush will be

[tex]\rightarrow \rm \dfrac{3x}{4} \times \dfrac{1}{6}=\dfrac{x}{8}[/tex]

Then the value of the paint set will be

[tex]\begin{aligned} \dfrac{3x}{4} +\dfrac{x}{8} + x &= 35.75\\\\\dfrac{15}{8}x &= 35.75\\\\15x &= 286\\\\x &= \$ 19.067 \end{aligned}[/tex]

Then the cost of the sketchbook will be

→ 3 × 19.067 / 4 = $ 14.3

Then the cost of the brush will be

→ $ 2.38

Answer:

Step-by-step explanation:

sorry for the bad handwriting lol

If the area of the triangle and the rectangle is 4 square cm and 2 square cm. Then the total surface area of the triangular prism will be 14 square cm.

A closed solid with two parallel triangular bases joined by a rectangle surface is known as a triangular prism.

The total surface area of the triangular prism will be

Total surface area = 2(area of the triangle) + 3(area of the rectangle)

The area of the rectangle will be

Rectangle area = 2 x 1

Rectangle area = 2 square cm

The area of the triangle will be

Triangle area = 0.5 x 4 x 2

Triangle area = 4 square cm

Then the total surface area will be

Total surface area = 2 x 4 + 3 x 2

Total surface area = 8 + 6

Total surface area = 14 square cm
