Answer:

9x+4x^2-5y

Step-by-step explanation:

Hi there!

Length of the field: 14x-3x^2+2y units

Width of the field: 5x-7x^2+7y units

To find how much greater the length of the field is than the width, subtract the width from the length:

14x-3x^2+2y-(5x-7x^2+7y)

Open up the parentheses

= 14x-3x^2+2y-5x+7x^2-7y

Combine like terms

= 14x-5x-3x^2+7x^2+2y-7y\\= 9x+4x^2-5y

Therefore, the length is 9x+4x^2-5y units greater than the width.

I hope this helps!

Find x <br><br>Plz help me!!!!
lbvjy [14]
Find the total ° of the shape.
(5-2) x 180°= 540°

x+21°+x = 540°-105°-154°-88°
2x+21° = 193°
2x = 193°-21°
2x = 172°
x = 172° ÷ 2
x = 86°

The perimeter of a rectangular painting is 364cm . If the length of the painting is 96cm, what is its width?
hram777 [196]

Answer:

The width would be 86cm

Step-by-step explanation:

Perimeter is (Width*2) +(Length*2)

Length is 96, multiply by 2 : 96*2 = 192

Subtract this from the total perimeter (364-192 = 172)

Divide this by 2 to get 1 width value (172/2 = 86)

86 cm

Approximate the change in the volume of a right circular cylinder of fixed radius requals21 cm when its height decreases from he
Tasya [4]
The volume of the cylinder is given by:
 V = pi * r ^ 2 * h
 For h = 12cm:
 V1 = pi * ((21) ^ 2) * (12)
 V1 = 16625.30832 cm ^ 3
 For h = 11.9cm:
 V2 = pi * ((21) ^ 2) * (11.9)
 V2 = 16486.76409 cm ^ 3
 The change in volume is given by:
 V1-V2 = 16625.30832-16486.76409
 V1-V2 = 138.54423 cm ^ 3
 Answer:
 the change in the volume is:
 V1-V2 = 138.54423 cm ^ 3
