Answer:

\text{Area of shaded region is }128 in^2

Step-by-step explanation:

Given the figure we have to find the area of shaded region.

As a square given of side 16 inches

\text{Area of square=}(side)^2=16^2=256 in^2

\text{Area of unshaded triangles=}\frac{1}{2}\times base\times altitude+\frac{1}{2}\times base\times altitude

=\frac{1}{2}\times 9\times 16 +\frac{1}{2}\times 7\times 16

=72+56=128 in^2

\text{Area of shaded region=area of square-area of unshaded triangles}\\=256-128=128 in^2

\text{Hence, area of shaded region is }128 in^2

Determine the equation of the linear function that generates the following table of values.
Mashutka [201]

Answer:

y = -19x + 14

Step-by-step explanation:

For each increase of x by 1, y decreases by 19, giving us -19x. When x = 0, y = 14, therefore, y = -19x + 14

Solve this quadratic equation.<br><br> 6x2 - 2x = 7
rjkz [21]

Answer:

x₁ = (1 + √43)/6

x₂ = (1 - √43)/6

Step-by-step explanation:

6x² - 2x = 7

6x² - 2x - 7 = 0

Formula

ax² + bx + c = 0

a = 6 ; b = - 2 ; c = - 7

x₁/₂ = [-b ± √(b²- 4ac)]/2a

x₁/₂ = (2 ± √4 + 4×6×-7)/12

x₁/₂ = (2 ± √172)/12

x₁/₂ = (2 ± 2√43)/12

x₁/₂ = 2(1 ± √43)/12

x₁/₂ = (1 ± √43)/6

x₁ = (1 + √43)/6

x₂ = (1 - √43)/6
