Mathematics
1 answer:
jeka57 [31]3 years ago

Answer:

x=3

Step-by-step explanation:

6                   10

---------- = ------------

6+x             15


using cross products

6 * 15  = 10 * (6+x)

90 = 60+10x

subtract 60 from each side

90-60 = 60+10x-60

30 = 10x

divide by 10

30/10 = 10x/10

3=x

The composite shape is made up of two identical triangles and two different rectangles. What is the are of the composite shape i
AfilCa [17]

Answer: 72 u^2

<h3>Explanation:</h3>

What we know:

  • Both triangles are identical
  • Both rectangles are different
  • There are values in units^2 given
  • There are right angles

How to solve:

We need to find the area of at least one of the triangles and double it. Then, we need to find the areas of both rectangles. Finally, we need to add these areas to find the total area. The final area will be represented in units squared (u^2)

<h2>Process:</h2>

Triangles

Set up equation                                                 A = 1/2(bh)

Substitute                                                           A = 1/2(4*3)

Simplify                                                               A = 1/2(12)

Solve                                                                   A = 6

Double                                                                     *2

                                                                           A = 12 u^2

Rectangles

Set up equation                                                 A = lh

Substitute                                                           A = (14)(3)

Simplify                                                               A = 42 u^2

Set up equation                                                 A = lh

Substitute                                                           A = [14-(4+4)](3)

Simplify                                                               A = (14-8)(3)

Simplify                                                               A = (6)(3)

Multiply                                                               A = 18 u^2

Total Area

Set up equation                                                 A = R1+R2+T

Substitute                                                           A = 42 + 18 + 12

Simplify                                                               A = 60 + 12

Solve                                                                   A = 72 u^2

Answer:

(a) x^2-2x=x \times (x+2) \\\\(b) 6x^2+12x=2\times 3 \times x \times ( x + 2) \\\\(c)  3x^3 - 9x=3\times x \times (x^2 -3) \\\\(d) 4x^2 +28 x^3 = 2 \times 2 \times x \times x \times ( 1+ 7x)

Step-by-step explanation:

To factorize, at first, do factorize all the terms then take the common terms out.

(a) x^2-2x

This can be written as

x^2-2x= x\times x + 2 \times x

Now, taking x commom from both the terms.

x^2-2x=x \times (x+2)

(b) 6x^2+12x

=2\times 3 \times x\times x + 2\times 2 \times 3 \times x

Now, taking 2\times 3\times x common from both the terms, we have

6x^2+12x=2\times 3 \times x \times ( x + 2)

This is the required factorization.

(c) 3x^3 - 9x \\\\

= 3 \times x \times x \times - 9\times x \\\\ 3x^3 - 9x=3\times x \times (x^2 -3)

This is the required factorization.

(d) 4x^2 +28 x^3

= 2 \times 2 \times x \times x + 2 \times 2 \times 7 \times x \times x \times x \\\\4x^2 +28 x^3 = 2 \times 2 \times x \times x \times ( 1+ 7x)

This is the required factorization.
