Originally a rectangle has dimensions 12“ x 8” if both sides or increase by the same amount the areas doubled. find the new dimensions. need it answered

In order to solve this equation, we must create a couple equations.

The equations of the area of the box is

So the original area of the box is 96, now we need to double to find our new box's dimension.

We can call this "added amount" x, so that we can solve the equation.  Instead of pluggin 12 and 8 in, we will add the "x" variable.

So our new equation will look like the following

So, now we just need to solve

So, we have two values of X, but since we are talking about distance, we must reject the negative number.  So we add 4" to each dimension of the box making the new dimensions

16x12in

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
