So 4x^2+-2x+-6 then multiply by 5 would be the Area of the entire rectangle using the formula A=bh

You'll get 4x^2 − 2x − 6

a = 5

b = 4x² - 2x - 6

The area is:

a · b = 5(4x² - 2x - 6) = 20x² - 10x - 30

Or you can add areas of shapes:

- blue: 5 · 4x² = 20x²

- pink: 5 · (-2x) = -10x

- green: 5 · (-6) = -30 <- a little strange, the length of a side shouldn't be negative

Sum of those areas is the area of entire rectangle: 20x² - 10x - 30

But the first option is easier here.

A label wraps around soup can with a radius of 4.3 cm and a height of 6 cm. What is the lateral surface area of the label of the

Soloha48 [4]

Answer:

$52\pi \text{ cm}^2\approx 162.11\text{ cm}^2$

Step-by-step explanation:

We have been given that a label wraps around soup can with a radius of 4.3 cm and a height of 6 cm. We are asked to find the lateral surface area of the label of the soup can in square centimeters.

We will use lateral surface area of cylinder to solve our given problem as:

$LA=2\pi rh$ , where,

r = Radius of cylinder,

h = height of cylinder.

Upon substituting our given values in above formula, we will get:

$LA=2\pi \times\text{4.3 cm}\times \text{6 cm}$

$LA=51.6\pi \text{ cm}^2$

$LA=162.10618\text{ cm}^2$

Therefore, the lateral surface area of the label of the soup is approximately 162.11 square cm.

A teacher is buying supplies for two art classes. For class 1, the teacher buys 24 tubes of paint, 12 brushes, and 17 canvasses.

Ede4ka [16]

Class 1 =$177.90
Class 2 =$159

Class 1

24 tube of paint / $3.35 each
12 brushes/ $1.75 each
17 canvases/$4.50 each
Total cost of paint= $80.40
Total cost of brushes=$21
Total cost of canvases= $76.50
Total spent on class 1 = $177.90

Class 2

20 tubes of paint/$3.35 each
14 brushes/$1.75 each
15 canvases/ $4.50 each
Total cost of paint=$67
Total cost of brushes =$24.50
Total cost of canvases=$67.50
Total spent on class 2 = $159
