2x+5+(6x+1)
you distribute an invisible one to get them out of the parentheses
2x+5+6x+1
You then add like terms

Answer:
The maximum value is 5
Step-by-step explanation:
Since this is an upside-down parabola, the maximum value occurs at the vertex. Using -b/2a, we can find the x-value of the vertex and use that x value to plug back into the original function to find the maximum value.
x = -b/2a = -(-12)/(2(-6)) = 12/-12 = -1
f(-1) = -6(-1)^2-12(-1)-1 = 5
Let
x---------> the maximum pairs of shoes that Amantha can buy with her savings
we know that
x=[1,140-80]/65-------> x=1,060/65------> x=16.30 pairs of shoes
therefore
the answer is
16 pairs of shoes
