Answer:

152 square inches

Step-by-step Explanation:

To answer this, please look at the picture below. We can find the area by separating and combine the value of areas after calculating three values for each areas. (Notice that when we separate them, we get three rectangles which we can use the formula of width × length)

We should get 80+48+24 which add up to 152.

Hi there!

The correct answer is: (x+8)² = 73

Step-by-step explanation:

First you want to modify the equation: x² + 16x - 6 = 3 into x² + 16x = 9 by adding 6 on both sides.

Then you analyze the new equation, if you can see, 16x is positive which means two positive numbers have to be added up to equal a positive. Which eliminates the choices that have (x-8)²

And now you are left with two choices:

(x+8)² =73 and (x+8)² = -55

Now remember, when you factor out (x+8)² it equals to x² + 16x + 64

next let's bring it back to the very first equation: x² + 16x = 9

now which choice matches the result x² + 16x = 9. The answer will be (x+8)² = 73 because when you subtract 64 on both sides you get 9.
