Answer:
13/14
Step-by-step explanation:
Area of a rectangle = l * b
=> 4 1/3 = 3 1/2 + b
=> (4 1/3) / (3 1/2) = b
=> (13/4) / 7/2 = b
=> 13/4 * 2/7
=> 13/2 * 1/7
=> 13/14
Therefore the width = 13/14

Refrection of (-20, 4) across x-axis gives (-20, 4) = (-20, -4)
Refrection of (-20, 4) across y-axis gives (20, 4)
Refrection of (-20, 4) across y = -x gives (20, -4)
Refrection of (-20, 4) across y = 7 gives (20, 10)
Answer:
-2a^4+8a^3-6a^2
Step-by-step explanation:
2a^2(a-1)(3-a)
2a^2(-a^2 +3a-3+a)
2a^2(-a^2+4a-3)
-2a^4+8a^3-6a^2
