a=3
b=1/2
then

where x represent every half a year.
Answer:
5
Step-by-step explanation:
because it is asking what minus 9 is equal to -4
Answer:
A = ± 
Step-by-step explanation:
Given
b²A² - 3g = q ( add 3g to both sides )
b²A² = q + 3g ( divide both sides by b² )
A² =
( take the square root of both sides )
A = ±

To find the answer we can use the angles sum of triangle which is 180° to find ∠z by deducting the other two angles from 180°:
180°-53°-90°
=37°
Therefore ∠z=37°.
