Answer:
area = x^2 - 4x
Step-by-step explanation:
a = x(x-4)
a = x^2 - 4x (x times x is x^2, x times -4 is -4x)
A. Four times a number increased by two is equal to twice the difference between the number and three
First, you can distribute the -2 to 1 - 7n
the new equation is 5n + 34 = -2 + 14n
then, you can add 2 to both sides to cancel the -2 on the right
now you have 5n + 36 = 14n
after this, you add -5n to both sides, again, to cancel the 5n on the left
you are left with 34 = 9n
lastly, divide both sides by 9 to find the value of n, which is 4.
