Answer:
Step-by-step explanation:
3x−7=4
1 Let x=\frac{11}{3}x=
3
11
.
3\times \frac{11}{3}-7=4
3×
3
11
−7=4
2 Cancel 33.
11-7=4
11−7=4
3 Simplify 11-711−7 to 44.
4=4
4=4

As we can see the given diagram represents an isosceles trapezoid.
So we can say from the properties of isosceles trapezoid.


As the required side XY has a length y+1, So we can write

Answer:
462 ways
Step-by-step explanation:
One book never selected means 12 - 1 = 11.
So to find the number of ways, 11C5 which equals to: 11!/(5!(11-5)!) = 462
Answer:
72w^3
how: factor 8w^3= 2^3 times w^3
factor 9w= 3^2 times w
multiply each factor with the highest power
2^3 times 3^2 times w^3
=72w^3
