Part A:SA = 3.14(rs + r^2)SA = 3.14((2)(3) + (2)^2)
Part B:SA = 3.14((2)(3) + (2)^2)SA = 3.14(6 + 4)SA = 3.14(10)SA = 31.4SA = 31.4 units^2

What is the completely factored form of p4 – 16? (p – 2)(p – 2)(p 2)(p 2) (p – 2)(p – 2)(p – 2)(p – 2) (p minus 2) (p 2) (p squa

The completely factored form of the provided polynomial is  (p -2) (p+ 2) (p² +4). The option 4 is the correct option.

<h3>What is polynomial?</h3>

Polynomial equations is the expression in which the highest power of the unknown variable is n (n is a real number).

The polynomial equation given in the problem is,

p^4 - 16

Let the factor form of the polynomial is f(p). Thus,

f(p)=p^4 - 16\\f(p)=p^4 - 2^4\\f(p)=(p^2)^2- (2^2)^2

Using the formula of difference of squares, we get,

f(p)=(p^2-4)(p^2+4)\\f(p)=(p^2-2^2)(p^2+4)\\f(p)=(p-2)(p+2)(p^2+4)

Thus, the completely factored form of the provided polynomial is  (p -2) (p+ 2) (p² +4). The option 4 is the correct option.

Describe the image of D first reflected across line l, then across line m.
Basile [38]
Answser: the image of D will be the same drawing (D), translated to the right of the line m.

Explanation:

1) The first reflection, accross the line l, will be the letter<span> D turned (with the "belly" to the left instead of the right), located to the right of the line l and to the left of the line m.

2) The second reflection, accross the line m, will turn the letter again leting it equal to the original picture, now translated to the right on the line m.
