Answer:
Option A. 
Step-by-step explanation:
we know that
The combined area of the 3 windowpanes and frame is equal to

using a graphing tool to solve the quadratic equation
The solution is 
see the attached figure
5x+3=3x+7
<em></em>-3 = -3
2x+3=7
-3= -3
2x=4
x=2
The one way to determine factors of x³ + 11x² – 3x – 33 will be
.
<h3>What is a factorization?</h3>
It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.
The steps involved in the factorization are;
1. For each pair of parentheses, we create a common factor.
2. We use x2 as a common factor for the first parenthesis.
3. We use common factor 3 for the second parenthesis.

We will find the final solution as
.
Hence the one way to determine factors of x³ + 11x² – 3x – 33 will be
.

We can simplify this equation and find the value of k.
k ÷ 2 + 1 - 1k = -2k
k ÷ 2 + 1 = -k
k + 1 = -2k
1 = -3k
k = -1/3
