Answer:
-24xy+ 162x²y +168xy²
Step-by-step explanation:
[4-7(3x+4y)] • 3x(-2y) =
(4-21x-28y) • (-6xy)=
4•(-6xy) -21x•(-6xy)-28y•(-6xy)=
-24xy+ 162x²y +168xy²

Answer:
Sin(E) = 
Step-by-step explanation:
The full question is as follows :
To find - In the accompanying diagram, what is sin E?
Proof -
We know that,
Sin(theta) = (opposite side) / (hypotenuse)
From the diagram, we can see that,
Base = 3
Perpendicular = 5
Hypotenuse = 5
So,
For angle E,
Opposite side = 4
Hypotenuse = 4
∴ we get
Sin(E) =
