Solution:
2(6+7)= 3(5+2)
Step ; 1 { Solving first Term i.e LHS }
LHS : 2 ( 6 + 7)
☞ 2 ( 13)
☞ 2 × 13
☞ 26
Now, RHS ; 3 ( 5 + 2)
☞ 3 ( 7)
☞ 21
From Equation 1 and 2, We can LHS and RHS are not Equal.
Therefore, 26≠ 21.

Answer:
<em>V(t) = π(4cos πt -5sinπt) cm</em>
Step-by-step explanation:
Given the displacement (in centimeters) of a particle moving back and forth along a straight line is given by the equation of motion s = 4 sin πt + 5 cos πt, where t is measured in seconds, the average velocity of the body will be expressed as the change in displacement of thee particle with respect to time.
This is expressed mathematically as V = ds/dt
Differentiate the displacement function to get the velocity V
V = 4πcos πt + (-5πsin πt)
open the parenthesis
V = 4πcos πt - 5πsin πt
bring out the common factor
V = π(4cos πt -5sinπt)
<em>Hence the average velocity of the body during each time is expressed as </em>
<em>V(t) = π(4cos πt -5sinπt) cm</em>
<em></em>
Just a straight line on the Y=4. It has a zero slope.
