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

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
