D. 28.54

Step-by-step explanation:

To find the area of the shaded region, find the area of the circle and divide it in 4. This will the area of the portion with the triangle.

Now, find the area of the triangle and subtract the two. The resulting value will be the area of the shaded region.

Circle:

$A = \pi r^2\\A = \pi 10^2\\A = 100 \pi\\A = 314$

Divide by 4 for the area of the section with the triangle.

314/4 = 78.5

Triangle:

$A = \frac{1}{2}bh\\A = 0.5 (10 )(10)\\A=0.5(100)\\A=50$

Subtract the two, 78.5 - 50 = 28.5.

Step-by-step explanation:

group the following terms together

[ x³ - 7x² ] + [ - 5x + 35 ] ← factor each group

= x²(x - 7 ) - 5(x - 7 ) ← factor out (x - 7 )

= (x - 7)(x² - 5 ) → C
