$86.62 would be the total after 15% tax.
Answer:
1. y = (3x^2 - 4)
2. y = (-x^2) + 2
3. y = (-x^2 - 8)
4. y = (3x^2 - 2) + 4
5. y = (3x^2 + 4)
6. y = (-1/4x^2)
Step-by-step explanation:
Step-by-step explanation:
In isoceles triangle two sides are equal and two angles are equal.
Then,
∠R = ∠T = (5x-40)°
Then,
∠RTS + ∠STU = 180° (bcoz it lies on a straight line)
(5x-40) ° + 5x = 180°
10x = 220°
x = 22°
Therefore,
Option A is correct✔
