Area = length x width
the "big" rectangle: length = 15,  width = 14
the blue rectangle is: length = 15 - 4,  width = 14 - 6
Area of blue rectangle = (15 - 4)(14 - 6)

Answer:
the x intercept is -4
Step-by-step explanation:
to find the x intercept, set y = 0 and solve for x
y = 5x+20
0 = 5x+20
subtract 20 from each side
-20 = 5x +20 -20
-20 = 5x
 divide each side by 5
-20/5 = 5x/5
-4 =x
