Answer:

8x³ + 6x² + 5x

Step-by-step explanation:

Let's simplify step-by-step.

−x^3 + 5x + 7x^2 + 8x^3 − ( −x^3 + x )

Distribute the Negative Sign:

= −x^3 + 5x + 7x^2 + 8x^3 + −1 ( −x^3 + x )

= −x^3 + 5x + 7x^2 + 8x^3 + −1 ( −x^3 ) + −1x

= −x^3 + 5x + 7x^2 + 8x^3 + x^3 + −x

Combine Like Terms:

= −x^3 + 5x + 7x^2 + 8x^3 + x^3 + −x

= ( −x^3 + 8x^3 + x^3 ) + ( 7x^2 ) + ( 5x + −x )

= 8x^3 + 7x^2 + 4x

Answer:

= 8x^3 + 7x^2 + 4x

Answer:

33

Step-by-step explanation:

f(4) = 4(4) - 3 = 16 - 3  =  13

g(-5) = -2(-5) + 10  =  10 + 10  =  20

13 + 20 = 33

Answer:

Area of sector = 132.78 cm² (Approx.)

Step-by-step explanation:

Given:

Angle created by sector = 90°

Diameter of circle = 13 centimeters

Find:

Area of sector

Computation:

Radius of sector = Diameter of circle / 2

Radius of sector = 13 / 2

Radius of sector = 6.5 centimeters

Area of sector = [θ/360]πr²

Area of sector = [90/360][22/7][13]²

Area of sector = [1/4][22/7][169]

Area of sector = [0.25][3.1428][169]

Area of sector = 132.78 cm² (Approx.)

Answer:

School X has 12 points and school y has 4 points.

Answer:

Wegman's, roughly 3 cents

Step-by-step explanation:

Divide the price by the number of paper towels in the pack to get the unit price.

$15.72/12= $1.31

$13.35/10= $1.335, round since it's money, $1.34

$1.34-$1.31= $0.03 or 3 cents

Wegmans has the better buy, as their unit price is lower.

The difference in unit prices between the two stores is $0.03 per paper towel.

To determine which store has the better buy, we need to compare the unit prices of paper towels at both Wegmans and Tops.

The unit price is the cost per paper towel.

For Wegmans:

Cost of 12 pack of paper towels = $15.72

Number of paper towels in the pack = 12

Unit price at Wegmans = Total cost / Number of paper towels

Unit price at Wegmans = $15.72 / 12 = $1.31 per paper towel

For Tops:

Cost of 10 pack of paper towels = $13.35

Number of paper towels in the pack = 10

Unit price at Tops = Total cost / Number of paper towels

Unit price at Tops = $13.35 / 10 = $1.34 per paper towel

Now, we compare the unit prices:

At Wegmans, the unit price is $1.31 per paper towel.

At Tops, the unit price is $1.34 per paper towel.

The store with the lower unit price has the better buy.

In this case, Wegmans has the better buy, as their unit price is lower.

To find the difference in unit prices:

Difference in unit prices = Unit price at Tops - Unit price at Wegmans

Difference in unit prices = $1.34 - $1.31 = $0.03 per paper towel

So, the difference in unit prices between the two stores is $0.03 per paper towel.

Without an image this would be unanswerable

Answer:

$135

Step-by-step explanation:

Step 1

Conversion

Base = 2 yards

1 yard = 3 feet

2 yards = x

Cross Multiply

x = 2 × 3 feet = 6 feet

Height = 5 yards

1 yard = 3 feet

5 yards = x

Cross Multiply

x = 5 × 3 feet = 15 feet

Step 2

Find the area of the triangle

Area of a triangle = 1/2 × base × height

Base = 6 feet

Height = 15 feet

Area = 1/2 × 6 × 15

= 45 square feet

Step 3

Find the cost of the carpet

1 Square foot = $3

45 square feet = x

Cross Multiply

x = 45 × $3

x = $135

Therefore, the amount you will pay to cover a triangular section of the floor is $135

Answer:

The answer to the given question is - ¹/₂

Step-by-step explanation:

Given;

[tex]\frac{2}{5} \times -\frac{3}{7} - \frac{1}{14} - \frac{3}{7} \times \frac{3}{5}[/tex]

Before we apply the distributive property, perform the multiplication operation.

[tex](\frac{2}{5} \times -\frac{3}{7}) - \frac{1}{14} - (\frac{3}{7} \times \frac{3}{5} )\\\\\frac{-6}{35} - \frac{1}{14} - \frac{9}{35}[/tex]

Now, apply the distributive property, to obtain the final answer,

In distributive property, the following rule is applied;

ax + ay = a(x + y)

[tex]\frac{-6}{35} - \frac{1}{14} - \frac{9}{35} = \frac{-1}{7} (\frac{6}{5} + \frac{1}{2} + \frac{9}{5} )= \frac{-1}{7} (\frac{12 + 5+ 18}{10} )= \frac{-1}{7} (\frac{35}{10} ) = \frac{-35}{70} = \frac{-1}{2}[/tex]

Therefore, the answer to the given question is - ¹/₂

Answer:

Step-by-step explanation:

Answer:

347.04 m²

Step-by-step explanation:

Total surface area = central rectangular prism + (1/2 left + 1/2 right)cylinder

a = 2x(11x3+11x6+6x3) + (2xπx(6/2)²+2xπx(6/2)x3)

  = 234 + 113.04

  = 347.04

She needs 3 3/4 cups more

Step-by-step explanation:

(I think you accidently put the 18 3/4 part twice) but anyways if you add 3/4 and 1/2 you get 1 and 1/4 that will be important later then you do 18 + 6 = 24 and then add your 1 and 1/4 to get a total of 25 1/4 then you just minus that from 29 and get 3 and 3/4
