An solution to an equation = 21 would be something like 2p + 7

if you wanna know how to solve this 
here is how:
<span>Simplifying 2p + 7 = 21 Reorder the terms: 7 + 2p = 21 Solving 7 + 2p = 21 Solving for variable 'p'. Move all terms containing p to the left, all other terms to the right. Add '-7' to each side of the equation. 7 + -7 + 2p = 21 + -7 Combine like terms: 7 + -7 = 0 0 + 2p = 21 + -7 2p = 21 + -7 Combine like terms: 21 + -7 = 14 2p = 14 Divide each side by '2'. p = 7 Simplifying p = 7</span>

igor_vitrenko [27]

Answer:

Length 7 feet and Width 5 feet

Step-by-step explanation:

we know that

The area of the rectangle ( a dining room table) is equal to

A=LW

where

L=(3x+1)\ ft

W=(3x-1)\ ft

A=35\ ft^2

substitute

35=(3x+1)(3x-1)

Apply difference of squares right side

35=9x^2-1

9x^2=36\\x^2=4\\x=\pm2

Remember that the length cannot be a negative number

so

x=2

<em>Find the length</em>

L=(3(2)+1)=7\ ft

<em>Find the width </em>

W=(3(2)-1)=5\ ft
