The equation which equivalent to given expression − 3 ( x − 6 ) + 12 x − ( 8 x + 3 ) is
- x+15
- ( 12 x − 11 x ) + ( 18 − 3 )
The Correct option is (C) and (E)
<h3>What is Linear equation in one variable?</h3>
A linear equation is an equation of a straight line, written in one variable. The only power of the variable is 1. Linear equations in one variable may take the form ax+ b = 0.
The given equation is:− 3 ( x − 6 ) + 12 x − ( 8 x + 3 ) .
= -3x+18 + 12 x -8x-3
=x +15
The corresponding equation to the above equation is:
C. x+15
D. (12 x - 11x) + (3-18)
= x-15
E. (12 x - 11x) + (18-3)
= x+15
F. (12 x - 11x) + (-6+3)
= x-3
As from the above it can be seen that the equation which equivalent to given expression − 3 ( x − 6 ) + 12 x − ( 8 x + 3 ) . is
- x+15
- ( 12 x − 11 x ) + ( 18 − 3 )

Answer:
a) distance from plane to swimmer = 2127.66 m
b) distance from swimmer to point D = 1928.31 m
Step-by-step explanation:
Given the question,
height at which the plane is = 900m
angle of depression = 25°
If we closely observe, the whole scene is making an right angle triangle
So, we can use trigonometry identities
<h3>a)</h3><h3>cosФ = BD / AB</h3>
cos (90-25) = 900 / AB
0.423 = 900 /AB
AB = 2127.66 m
<h3>b)</h3><h3>sinФ = AD/AB</h3>
sin(90-25) = AD /2127.66
AD = sin(90-25) x 2127.66
AD = 1928.31m
