How are a trapezoid and a rectangle different

Answers

Answer 1
Answer: -- Both pairs of sides of a rectangle are parallel.
Only one pair of sides of a trapezoid are.

-- A rectangle is a parallelogram.
A trapezoid isn't.

-- The opposite sides of a rectangle are equal.
The opposite sides of a trapezoid aren't.

-- All of the angles of a rectangle are right angles.
The angles of a trapezoid aren't.

-- The area of a rectangle is the product of (length) times (width).
The area of a trapezoid is (height) times (the average of the two bases).


Answer 2
Answer: A trapezoid has two perpendicular sides, and a rectangle has 4 parallel sides.

What is the graph of the system y= -2x + 3 and 2x + 4y= -8

Answers

y = -2x + 3
2x + 4y = -8

y = -2x + 3
y + 2x = 3

2x + 4y = -8

Subtract those equations
3y  = -11
y = -11/3

y = -2x +3
-11/3 = -2x + 3
2x = 3 + 11/3
x = 3/2 + 11/6
x = 20/6
x = 10/3

therefore above lines will intersect in this ( 10/3 , -11/3 ) coordinates

Answer:

The answer to your question is   Momentum  = ((x + 2)^(2))/(x - 3)

Step-by-step explanation:

Data

mass = (x^(2)+ 4x + 4 )/(x^(2)- 9)

velocity = (x^(2)+ 5x + 6)/(x + 2)

Formula

Momentum = mass x velocity

Substitution

    Momentum = (x^(2)+ 4x + 4)/(x^(2)- 9) (x^(2) + 5x + 6)/(x + 2)

Factor    The first numerator is a perfect square trinomial and the second one is a trinomial of the form x² + bx + c.

    Momentum = ((x + 2)^(2))/((x - 3)(x + 3)) ((x + 2)(x + 3))/(x + 2)

Simplify and result

   Momentum  = ((x + 2)^(2))/(x - 3) or (x^(2) + 4x + 4)/(x - 3)

Find the degree of the monomial. 6x8y5

Answers

Answer:

13

Step-by-step explanation:

We have been given the monomial 6x^8y^5

Here the variables are x and y.

In order to find the degree this monomial, we add the exponents of the variables x and y.

Exponent of x = 8

Exponent of y = 5

Therefore, the degree of the monomial is

Degree = exponent of x + exponent of y

Degree = 8 + 5

Degree = 13

. 6x⁸y⁵ ← x is a factor 8 times, and y is a factor 5 times, so the degree is 8+5=13

Perdita goes to the fruit market with $9 to buy avocadoes. Each avocado costs $2. Write and solve an inequality to find the greatest number of avocadoes Perdita can buy

Answers

let x= number of avocadoes she can buy
let y= total cost

y= 2x 

9= 2x     9/2= 4.5
4.5= x
(you cannot cut the avocado in half therefore your answer is simply 4)
