Answer:
![5(x-2)^2](https://tex.z-dn.net/?f=5%28x-2%29%5E2)
Step-by-step explanation:
![5x^2-20x+20=\\5(x^2-4x+4)=\\5(x-2)^2](https://tex.z-dn.net/?f=5x%5E2-20x%2B20%3D%5C%5C5%28x%5E2-4x%2B4%29%3D%5C%5C5%28x-2%29%5E2)
That's 21.
Hope this helps !

X-intercept = 25.
y-intercept = -20.
To find the x or y intercept you're trying to find the point in which the line crosses that particular axis. In other words, you would want to find what x equals when y is zero and what y equals when x is zero.
- 4(0)-5y=100 : 5y=100, 100/5= 20, y-intercept = -20
- 4x-5(0)=100 : 4x=100, 100/4= 25, x-intercept = 25
- x-intercept is (25,0) ; y-intercept is (0,-20)

Answer:
y = 12
Step-by-step explanation:
Triangles ABD and CBD are congruent, so DA = DC:
3y +6 = 5y -18
24 = 2y . . . . . . . . add 18-3y; next, divide by 2
12 = y

<em>Additional comment</em>
In some variations of this question, you may be asked to solve for x. Since the angles are equal, you have ...
3x -1 = 34 -2x ⇒ 5x = 35 ⇒ x = 7 . . . (consistent with ∠ABC = 40°)
