Mathematics

Answer:

Step-by-step explanation:

Because every triangle that can ever be made has three sides, you can open up the triangle so that it becomes a straight horizontal line. A horizontal line is also 180 degrees which is why this idea works with triangles.

This is because two angles are zero and top is a straight line, and a line is 180 degrees!

Factor completely, then place the answer in the proper location on the grid. <br> 6х^2 - 3х - 30
Tems11 [23]

Answer:

3(x + 2)(2x - 5)

Step-by-step explanation:

Given

6x² - 3x - 30 ← factor out 3 from each term

= 3(2x² - x - 10) ← factor the quadratic

Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term

product = 2 × - 10 = - 20 and sum = - 1

The factors are + 4 and - 5

Use these factors to split the x- term

2x² + 4x - 5x - 10 ( factor the first/second and third/fourth terms )

= 2x(x + 2) - 5(x + 2) ← factor out (x + 2) from each term

= (x + 2)(2x - 5), thus

2x² - x - 10 = (x + 2)(2x - 5) and

6x² - 3x - 30

= 3(x + 2)(2x - 5) ← in factored form

7. Find DE.<br> 11-25<br> E<br> А<br> 4x + 1<br> D<br> С
Arlecino [84]

Answer:

  • DE = 37

Step-by-step explanation:

AD = DC and BE=EC ⇒

DE = 1/2AB

  • 4x + 1 = 1/2(11x - 25)
  • 2(4x + 1) = 11x - 25
  • 8x + 2 = 11x - 25
  • 11x - 8x = 2 + 25
  • 3x = 27
  • x = 27/3
  • x = 9

DE = 4*9 + 1 = 36 + 1 = 37
