Answer:
1,3
Step-by-step explanation:
=(x^2-1)(x^2-9)=0
x=1,x=3
Answer:
The answer to your question is x = 4d/t - S1
Step-by-step explanation:
Data
total time = t = 2.75 hours
Initial speed = S1 = 55 mi/h
Final speed = x
distance = d = 60 mi
Formula
speed = distance / time
Average speed = (Initial speed + final speed)/2 or
= (S1 + x)/2
Substitution
(S1 + x)/2 = 2(d) / t
Solve for x
x = (2d/t)2 - S1
Simplification and result
x = 4d/t - S1
where A is area
a is side a lets say its 8cm
b is side b lets say its 7 cm
theta is 28
Answer:
either 45$ a year or divide it to days/months
Step-by-step explanation:
X - 14 = 52
move - 14 for + 14
x = 52 + 14
x = 66
