Answer:

8(y + 3)(y + 4)

Step-by-step explanation:

Factor out 8 from each term

= 8(y² + 7y + 12) ← factor the quadratic

Consider the factors of the constant term (+ 12) which sum to give the coefficient of the y- term (+ 7)

The factors are + 3 and + 4, since

4 × 3 = 12 and 4 + 3 = 7, hence

y² + 7y + 12 = (y + 3)(y + 4), and

8y² + 56y + 96 = 8(y + 3)(y + 4) ← in factored form

Answer:

The area of the shaded region is 148.04 cm².

Step-by-step explanation:

It is provided that a 7 cm × 5 cm rectangle is inside a circle with radius 6 cm.

The sides of the rectangle are:

l = 7 cm

b = 6 cm.

The radius of the circle is, r = 6 cm.

Compute the area of the shaded region as follows:

Area of the shaded region = Area of rectangle - Area of circle

$=[\text{l}\times\text{b}]-[\pi\test{r}^{2}]\\\\=[7\times5]+[3.14\times 6\times 6]\\\\=35+113.04\\\\=148.04$

Thus, the area of the shaded region is 148.04 cm².
