-4(4x+3) + (7x -2) = (-16x + -12) + (7x + 2) = -16 + -12 + 7x + 2 = -9x -10
The answer is -9x -10
LB = 343,000
<span>B = 343,000 / L </span>
<span>minimizing perimeter is same as minimizing semi-perimeter S </span>
<span>S = L + B = L + 343,000 / L </span>
<span>S' = 1 - 343,000 /L^2 </span>
<span>setting S' to zero & taking the +ve value, </span>
<span>L = sqrt(343,000) = 585.66 m </span>
<span>since a rectangle with integer sides is wanted, </span>
<span>dimensions = 585 m x 586 m </span>

Ignore it because the answer to 51*37 is 1,887 not 1,500 which means that they are reducing it not rounding it.
Answer:
She now has $0 left because all together, she takes out $27 which is all she had in her account so it leaves her with $0
Using the vertex of the quadratic function, it is found that:
a) The maximum number of customers in the store is at 12 P.M.
b) 75 customers are in the store at this time.
The number of customers in x hours after 7 AM is given by:
Which is a quadratic equation with coefficients
Item a:
The maximum value, considering that a < 0, happens at:
Hence:
5 hours after 7 A.M, hence, the maximum number of customers in the store is at 12 P.M.
Item b:
The value is y(5), hence:
75 customers are in the store at this time.
