I am assuming your teacher wants you to solve for v.
Therefore we need to isolate v, first step will be moving 2 to the other side then multiplying both sides by 11.
4=v/11-2
4+2=v/11
6=v/11
6*11=v/11*11
66=v
v=66
Check answers: substitute v=66 back into the equation.
right hand side:66/11-2=6-2=4
left hand side:4
RHS=LHS therefore the solution is correct.
Done!
Hope this helped, if there are any questions just ask them in the comments and I will answer them.
D= difference in height
A= Alex's height (1.6m) N= Noah's height (1.5A)
Step 1:
D=N-A
substitute N= 1.5 A in for N
D= 1.5(1.6) - 1.6
D= 2.4 - 1.6
D= 0.8 m difference in height
Step 2:
Convert meters to centimeters 1 m = 100 centimeters
0.8 x 100-80cm
Noah is 80cm taller than Alex.
Hope this helps! :)
The actual factor is 6(x + 1)(x^2 - x +1).
