Answer:
3:1 or 3
Step-by-step explanation:
the left triangle is scaling up to the right triangle. 5/15 is 1/3
7/21 is 1/3
4/14 is 1/3
since it is scaling UP, the scale factor is 3:1

Answer:
x = 37
Step-by-step explanation:
The angle on the left (x+15) and the angle on the right (4x-20) put together would have to equal 180 since a straight like is 180 degrees. If you add like terms the problem would be 5x-5=180. You would have to add 5 (since its negative in the problem) to 180, making the problem 5x=185. Now you divide by 5 (since it's multiplied by 'x') by both sides, which makes your answer x=37

Step-by-step explanation:
To factorise the quadratic
Consider the factors of the product of the x² term and the constant term which sum to give the x- term
product = 6 × - 4 = - 24 and sum = - 5
The factors are + 3 and - 8
Use these factors to split the x- term
6x² + 3x - 8x - 4 = 0 ( factor the first/second and third/fourth terms )
3x(2x + 1) - 4(2x + 1) = 0 ← factor out (2x + 1)
(2x + 1)(3x - 4) = 0
Equate each factor to zero and solve for x
2x + 1 = 0 ⇒ 2x = - 1 ⇒ x = - 
3x - 4 = 0 ⇒ 3x = 4 ⇒ x = 
Solutions are x = - , x =
