That answer your looking for is 80
Here, ∠WVX = ∠WZY
& ∠W = ∠W [ Reflexive Property ]
Triangles have the constant sum, so they would be: equal.
WVX + WXV + W = W + WZY + WYZ
WXY = WYZ [ ∠WVX = ∠WZY ]
Now, As all the angles are equal, we conclude:
ΔXVW ≈ ΔYZW [ By ASA Postulate ]
Hope this helps!
Start by finding 7% of the $23.20:

Now add this to $23.20:

Now, let's find 18% of this new total with tax to find the tip amount:

This is the tip amount. And finally, let's add this to the 24.824:

Not sure if you were given any instructions about rounding, but Ana's cost will be around $29.29.
Hope this helps.
So b=-2 so you plug b in
l(-2)l + (-2)^3.
The absolute value of -2 is just 2 so now it is
2 + (-2)^3.
-2 * -2 is 4 but 4 * -2 is -8. So 2 + (-8) or 2 - 8 which comes to equal (-6) or negative six.
