Answer:
A. 
B. 
Step-by-step explanation:
A. The area of the shaded region = area of the whole large square - area of the 4 smaller squares
= (5x*5x) - 4(4*4)
Area of shaded region = 
B. The expression, , is the difference of two perfect squares, 25x² and 64. Therefore, apply the rule of factoring difference of two perfect squares.
Thus, 
Therefore, the expression of the are of the shaded region can be expressed in factored form as:

Answer:
y>5/3-3
Step-by-step explanation:
the two points graphed are (0,-3) and (3,-2)
what you're trying to find is the inequality between y and the slope, so first you need to find the slope
the formula for finding the slope is (y2-y1)/(x2-x1)
substitute your two points for your formula:
-2-3=-5
3-0=0
5/3 is your slope
your y intercept is -3 and we know this because it is the location of y when x=0
so your slope is 5/3 and your y intercept is 3, so now you decide howto write the inequality .
the shaded part is above the line and the line is dotted, so how you know to use the > sign
put it all together and you get y>5/3-3
