Step-by-step explanation:

QS = QR + RS

9x -4 = 2x -1 + (4x +17)

9x- 4 = 6x +16

9x - 6x= 16+ 4

3x= 20

x= 20/3= 6.66

Answer:

x = 22/3

Step-by-step explanation:

QR + RS = QS

=> 2x + 1 + 4x + 17 = 9x - 4

-3x = -22

x = 22/3

Helen [10]

The quadratic equation use to determine the thickness of the frame, x is 4x² + 10x - 1 = 0.

The correct option is D.

<h3>What is a quadratic equation ?</h3>

A quadratic equation is an algebraic equation of the second degree in x.. The quadratic equation is written as ax2 + bx + c = 0, where x is the variable, a and b are the coefficients, and c is the constant term.

<h3>According to the given information:</h3>

Total area  = 7 square feet

and,

Total area = Length x Width

So,

7 = (2x + 3)(2x + 2)

7 = 4x2 + 4x + 6x + 6

7 = 4x2 + 10x + 6

4x2 + 10x + 6 - 7 = 0

4x2 + 10x - 1 = 0

Hence,

The quadratic equation use to determine the thickness of the frame, x is 4x² + 10x - 1 = 0.
