It should be 4(x+5) which gives 4x+20
Answer:
(-6, -8) and (6, -8)
Step-by-step explanation:
Think of this as a right triangle
The hypotenuse is 10
The "y" leg is |-8| = 8
x² + 8² = 10²
x² + 64 = 100
x² = 36
x = ±6
two points
(-6, -8) and (6, -8)
978 x .05 = 48.9 should be the tax.
1% of 19,500= 195
6% = 1%x6 = 195x6 = 1170
19500+1170=20670
