Its easier to ask somebody face-to-face dude
Step-by-step explanation:
t = 9x, and dx = 1/9 dt.
∫ sin(9x) dx
= ∫ sin(t) (1/9 dt)
= 1/9 ∫ sin(t) dt
= -1/9 cos(t)
= -1/9 cos(9x)
An equation is formed of two equal expressions. The value of x in the given exponential equation is 10. The correct option is 10.
<h3>What is an equation?</h3>
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
In the given exponential equation 
, It can be observed that the base of both the sides of the equation is the same, therefore, 5. Therefore, the equation can be written as,
Since the base on both the sides are the same, comparing the exponential values on both sides,
x - 2 = 8
x = 8 + 2
x = 10
Hence, the value of x in the given exponential equation is 10.

Hello there!
The answer to this question will be answer choice A.
When using the SAS postulate, we need two pairs of sides and the pair of the angles between those two sides to be congruent.
It is given that one pair of sides are congruent, along with a pair of congruent angles.
We want the congruent angle to be between two congruent sides, thus AC must be congruent to EC in order for these triangles to be proven congruent by the SAS postulate.
Hope this helps and have an awesome day! :)
