6(x+9) = 7(x-4)
6x+54 = 7x-28
54 = x-28
82 = x
The number is 82.
Let us first assume that the operator between 5x^3 and 3 is addition. What Louise did was incorrect, as she did not follow the proper way of expanding a binomial. The actual steps to take when taking the square of a binomial is as follows:
(5x^3 + 3)^2 = (5x^3 + 3)(5x^3 + 3)
25x^6 + 15x^3 + 15x^3 + 9
25x^6 + 30x^3 + 9
The actual answer is <span>25x^6 + 30x^3 + 9.</span>
To find the average speed she goes in one mile, simply divide 21 by 4, this gives you 5.25.
To get the answer for part B, divide 42 by 5.25, Wich gives you 8. You can always check your work by doing the opposite as you did to solve, so 8 x 5.25 should equal 42, which it does.
