Sum, difference, and product..help!
taurus [48]

The sum of the function will be (r – s)(x) = –2x² + x – 3, The difference of the function will be (r – s)(x) = –2x² + x – 3, and The product of the function will be (r × s)(x) = 2x³ – 6x².

The complete question is attached below.

<h3>What is Algebra?</h3>

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

The functions are given below.

r(x) = x – 3

s(x) = 2x²

The sum of the function will be

(r + s)(x) = x – 3 + 2x²

(r + s)(x) = 2x² + x – 3

The difference of the function will be

(r – s)(x) = (x – 3) – 2x²

(r – s)(x) = –2x² + x – 3

The product of the function will be

(r × s)(x) = (x – 3) (2x²)

(r × s)(x) = 2x³ – 6x²

The area of a rectangular garden is 38 1/4 square meters the width of the garden is 4 1/2 meters what is the length of the garde
Snowcat [4.5K]

Hello...

Area is measured by the formula A=L*W (Area = Length X Width)  We know the area is 38 1/4 and the width is 4 1/2. It is easiest to convert them to decimals and solve. 38 1/4 = 38.25 and 4 1/2= 4.5 .    so, 38.25 = 4.5 * W

To solve for Width, we need to isolate it by getting 4.5 on the other side. To do this, we divide by 4.5 on both sides of the equals sign. this will give us W=8.5 or Width = 8 1/2 meters.
