Sketch the graph of 4 x squared + 25 x minus 21 using your graphing calculator. What are the x-intercepts of this graph? a. Negative three-fourths, 7 b. Three-fourths, negative 7 c. Negative three-fourths, negative 7 d. Three-fourths, 7 Please select the best answer from the choices provided A B C D

-2 is the right

statement #3: proof- ang is congruent to ang ecd : angles are congruent.  

step-by-step explanation:

1: the missing angles in statement #3  

a.) acb  

reason- the reason why the answer is acb is because angle ecd and angle acb are both the same size *that's what the word congruent means this is really simple.  

2: the missing word in reason #3  

c.) vertical  

reason- the reason why the answer is vertical is because the angles in that diagram on figure 2 is slanted, which is vertical, and the e and a both lay on vertical lines. along with the other's, but e and a are the 2 main points you want to focus on. and c is kind of like your starting point, because c is for both angles, not just one.  

i hope that was and understanding.
