Answer:
u = ± 4
Step-by-step explanation:
Given
u² = 16 ( take the square root of both sides )
u = ±
= ± 4
u = - 4, u = 4
Well lets do this
3 + 16 ÷ 4
we divide first
3 + 4
Addition
=7
Answer:
The dryer is 375 dollars
Step-by-step explanation:
The equation would be
664=(D)+(D-86) or
664=(375)+(375-86)
Rationalize the numerator:

This is continuous at
, so we can evaluate the limit directly by substitution:
