PLEASE HELP<br><br> Find the surface area of the triangular prism.
ASHA 777 [7]

Answer:

139

Step-by-step explanation:

First, find all the faces that you must find the areas of. In this case, you need to find the areas of two triangles and three rectangles.

In this triangular prism, the base is one triangle. If the area of the base is 7.75, we can assume that that holds true for both bases, and multiply 7.75 by 2 in order to find the area of both triangles.

Now find the area of each of the three rectangles by multiplying their individual heights and bases by each other. You should get 38, 47.5, and 38 as the areas of the rectangles.

Now add all the individual area's together. (They're bolded for clarity).

Factorise 5x + 40 <br> 7x - 49<br> 18x + 9<br> 15x - 10
Vera_Pavlovna [14]

<em><u>Factorization is:</u></em>

5x+40=5(x+8)\\\\7x-49=7(x-7)\\\\18x+9=9(2x+1)\\\\15x-10=5(3x-2)

<h3><u>Solution:</u></h3>

Given that we have to factor the given expressions

<h3><u>First expression:</u></h3>

5x + 40

We have to take the greatest common factor out

When we find all the factors of two or more numbers, and some factors are the same then the largest of those common factors is the Greatest Common Factor

Take G.C.F of 5 and 40

The factors of 5 are: 1, 5

The factors of 40 are: 1, 2, 4, 5, 8, 10, 20, 40

Then the greatest common factor is 5

Factor out 5 from given expression

5x + 40 = 5(x+8)

<h3><u>Second expression:</u></h3>

7x - 49

Similarly, take G.C.F of 7 and 49

The factors of 7 are: 1, 7

The factors of 49 are: 1, 7, 49

Then the greatest common factor is 7

Factor out 7 from given expression

7x - 49 = 7(x-7)

<h3><u>Third expression:</u></h3>

18x + 9

Similarly, take G.C.F of 18 and 9

The factors of 9 are: 1, 3, 9

The factors of 18 are: 1, 2, 3, 6, 9, 18

Then the greatest common factor is 9

Factor out 9 from given expression

18x + 9 = 9(2x+1)

<h3><u>Fourth expression:</u></h3>

15x - 10

Similarly, take G.C.F of 15 and 10

The factors of 10 are: 1, 2, 5, 10

The factors of 15 are: 1, 3, 5, 15

Then the greatest common factor is 5

Factor out 5 from given expression

15x-10 = 5(3x-2)

Thus factorization is found
