The length of a rectangle is 1 less than twice the width. The area of the rectangle is 28 square feet. Which equation represents the situation?

Answers

Answer:

2W²-W-28 = 0 is the equation.

Step-by-step explanation:

To form the equation we should always follow the statement as said.

First statement is

The length (L) of a rectangle is 1 less than twice of width (W).

Means L = 2W - 1 -------(1)

Second statement

Area of the rectangle is 28 feet²

Means L×W = 28 ------(2)

Now by putting the value of L from equation 1 to equation 2.

(2W - 1)×W = 28

2W² - W = 28

2W² - W - 28 = 0

This the equation that represents the situation.

2w^2 - w - 28 = 0, I dont know how this is right but it is

What is 2x116 and 4x17

Answers

2* 116
= 2*(100+16)
= 2*100+ 2*16 ( distributive property)
= 200+ 32
= 232

The final answer is 232~

4*17
= 4*(10+7)
= 4*10+ 4*7 (distributive property)
= 40+ 28
= 68

The final answer is 68~

For 2times116 =232 and for 17times4=68

Erik and Nita are playing a game with numbers. In the game, they each think of a random number from zero to 20. If the difference between their two numbers is less than 10, then Erik wins. If the difference between their two numbers is greater than 10, then Nita wins. I pick Erik won and they asked,Use your previous answers to write an algebraic statement that represents all the ways your player will win. Be sure to define your variable

Answers

An algebraic statement that represents all the ways Eric will wins is $|x-y|<10$ , where $x$ be the number that Eric thinks and $y$ be the number that Nita thinks.

If the difference between their two numbers is less than $10$ , then Erik wins. If the difference between their two numbers is greater than $10$ , then Nita wins.
