I don't know, but you could look it up on khan academy.
Answer: 264.0625
8•2 is 16 + 1/4 and then 16 1/4 squared
No and here’s why
you input the number into your inequality
9>2(7)+1
when you simplify that you get
9>15
and 9 is NOT greater than 15 so no it is not a solution to the inequality
Answer:
The triangles Δ VWZ and Δ VXY are similar by AA criteria.
Step-by-step explanation:
See the attached diagram.
Here, VZ = 16 in and ZY = 8 in. Again, VW = 18 in and WX = 9 in.
Therefore, 
So, line WZ divides the lines VY and VX in the same ratio 2 : 1.
So, Line WZ ║ Line XY
Hence, ∠ XYV = ∠ WZV {The corresponding angles as VY is a transverse}
Again, ∠ YXV = ∠ ZWV {The corresponding angles as VX is a transverse}
Therefore, the triangles Δ VWZ and Δ VXY are similar by Angle-Angle i.e. AA criteria. (Answer)
