Here is your answer:
4x² + 28x + 49
4x² + 14x + 14x + 49
2x(2x) + 2x(7) + 7(2x) + 7(7)
2x(2x + 7) + 7(2x + 7)
(2x + 7)(2x + 7)
(2x + 7)²
= 28
Hope this helps!
You just have to multiple the number times 4
Well, first they're assuming that the m<ABC = 90
The value of m<ABC is not given, so they aren't allowed to make up values based on the way the picture looks.
It is given that BD bisects <ABC, which means it splits the angle evenly..
Giving this equation: (x-5) = (2x-6)
Solving for x
-5 + 6 = 2x - x
1 = x
Answer:
C
Step-by-step explanation:
Plotting the points in a sketch quickly shows that the vertices are not at right angles to each other, thus excluding rectangle and square whose vertices are at right angles.
The best selection is a rhombus
