First you want to write 7x as a sum or difference: 15x-8x
Now, the expression would look like this: 10x^2+15x-8x-12
Next, factor out the 5x and -4 from the expression: 5x(2x+3)-4(2x+3)
Now, factor out the 2x+3 from the expression and you have your answer:
(2x+3)(5x-4)

The length of the base of a triangle is twice its height. if the area of the triangle is 169 square​ kilometers, find the height
Alik [6]

Answer:

  13 km

Step-by-step explanation:

The area formula for a triangle is ...

  A = (1/2)bh

We are told that b=2h, so this becomes ...

  A = (1/2)(2h)(h) = h²

Substituting the given area, we can find h:

  169 km² = h²

  (√169) km = h = 13 km

The height is 13 km.
