Answer: 17
Step-by-step explanation:
4y^2 + 2 - 2 = 38 - 2 (subtract both side by 2)
4y^2 = 36
Divide by 4:
y^2 = 9
y = 
y = 3
Answer:
You can multiply the brackets to make sure you get 4x² + 4x + 1. Since the numbers in the brackets are the same, we can just use one of them and let it equal to 0. Then solve it. ∴ The answer is x = -1/2.
Step-by-step explanation:
4x2+4x+1=(2x+1)2 or (2x+1)(2x+1)
Answer: D) x>2.
This is because the slope of the exponential function is clearly greater than the linear function from 2 on the x=axis forward.
The volume would be 124,000m2 or (1.24 x 10^2).
