Answer:

Your answer is correct!

Step-by-step explanation:

2 with an exponent of 4 you multiply the number (2) the amount of times as the exponent (4)

Then you remember PEMDAS

Parenthesis

Exponents

Multiplication

Division

Addition

Subtraction

So, once you do your exponent you multiply 8 and 2 which equals 16. Then you divide 16 by 4 which equals 4.

Lastly, you subtract 16 and 4 which equals 12.

Hope this helps!

An architect is designing square windows with an area of(x2 + 16x +64) ft?. The dimensions of the
Darina [25.2K]

A) The dimensions are (x+10) by (x+10).

B) The perimeter is given by 4x+40.

C) The perimeter when x is 4 is 56.

The quadratic can be factored by finding factors of c, the constant, that sum to b, the coefficient of x.  Our c is 100 and our b is 20; we want factors of 100 that sum to 20.  10*10=100 and 10+10=20, so those are what we need.  This gives us (x+10)(x+10 for the factored form.  

Since the dimensions are all (x+10), and there are 4 sides, the perimeter is given by 4(x+10).  Using the distributive property we have 4*x+4*10=4x+40.

To find the perimeter when x=4, substitute 4 into our perimeter expression:

4*4+40=16+40=56.
