Answer:

The answer to your question is: (7, 3)

Step-by-step explanation:

Equations

                               4x - 5y = 13      (I)         1.- Assign numbers to each equation

                               6x + 2y = 48    (II)

2.- Multiply (I) by 3 and (II) by -2

                               12x - 15y = 39      (I)'

                              -12x - 4y  = -96     (II)'

3.- Sum the equations

                             

                                0 - 19y = -57                      

4.- Find y

                                        y = -57/-19

                                        y = 3

5.- Find x

                              4x - 5(3) = 13                 Substitution

                              4x - 15 = 13                    Simplifying

                              4x = 13 + 15

                              4x = 28

                               x = 28/4

                              x = 7

Result

                            (7, 3)

Determine whether a triangle can be formed with the given side lengths. If so, use Heron's formula to find the area of the trian
marysya [2.9K]

Answer:

a, b, and c can be formed a triangle

The area of the triangle is 13385.87 square units.

Step-by-step explanation:

<em>Let us revise an important fact in any triangle</em>

  • The sum of the lengths of the two shortest side must be greater than the length of the longest side

The length of the sides are a = 240, b = 132, and c = 330

∵ The two shortest sides are a = 240 and b = 132

∵ a + b = 240 + 132 = 372

∵ The longest side is c = 330

∵ 372 > 330

∴ a + b > c

∴ a, b, and c can be formed a triangle

<em>Let us revise the </em><em>Heron's formula</em><em> of the area of the triangle</em>

  • Area = \sqrt{p(p-a)(p-b)(p-c)}, where a, b,c are the lengths of the sides of the triangle, and p=\frac{a+b+c}{2}

∵ p=\frac{240+132+330}{2}=351

∴ Area = \sqrt{351(351-240)(351-132)(351-330)}

∴ Area = \sqrt{351(111)(219)(21)}

∴ Area=13385.87

The area of the triangle is 13385.87 square units.
