Answer:
x = √(10) - 2, -√(10) - 2
Step-by-step explanation:
x² + 4x + 4 = 10
factor:
(x + 2)² = 10
take square root of both sides:
x + 2 = ±√(10)
split into 2 equations:
x + 2 = √(10) x + 2 = -√(10)
solve both equations and collect solutions:
x = √(10) - 2, -√(10) - 2
Answer:
90 seconds
Step-by-step explanation:
To find the time it takes to take a certain amount of steps, divide the given rate by the time.
3/2 = 1.5
This means she takes 1.5 steps every second. Now, we can multiply this rate by 60 to find how far she will go in that time.
1.5 · 60 = 90
Bethany takes 90 steps in 60 seconds.
I hope this helps ^^ Good luck

Answer:
x = 5
Step-by-step explanation:
3x + 2(2x − 1)= 33
simplify
3x + 4x - 2 = 33
7x - 2 = 33
add 2 to both sides
7x - 2 + 2 = 33 + 2
7x = 35
divide both sides by 7
7x/7 = 35/7
x = 5
