Half of 20 the line is in the middle of the triangle
4x^2+28x+49
4x^2+14x+14x+49
2x(2x)+2x(7)+7(2x)+7(7)
2x(2x+7)+7(2x+7)
(2x+7)(2x+7)
(2x+7)^2
The missing term is 28.
Answer:
The line passes through (1,1) and (3,2). Therefore, its equation is

Answer:

Step-by-step explanation:
(2x + 3) (-x - 2)
distribute first term, to the second term:
2x(-x) + 2x(-2) + 3(-x) + 3(-2)
multiply:
+ (-4x) + (-3x) + (-6)

combine the like terms:
- 4x - 3x - 6
-7x
- 7x - 6
final answer :
- 7x - 6
hope this helped !!
mark me brainliest :D
