2. Use addition and subtraction to simplify the following polynomials. A. Add polynomials: (3 - 4x + 8x2) + (-6 + 2x - 5x2)
Step 1: Rewrite the polynomials without the parentheses. (1 point)
Step 2: Write the polynomial in descending order and use parentheses around like terms. (1
point)

Step-by-step explanation:

The question looks incomplete; However, it can be answered based on the available data

Given

Required

Add

Step 1: Rewrite without bracket

Step 2: Arrange in descending order

Step 3: Perform Arithmetic Operations

The expression cannot be simplified any further;

Hence, the addition of is equivalent to

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius

: )

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
